Today, we delve into the fascinating world of Geographic Information Systems (GIS) analysis through the eyes of Tara Srinivasan. Tara, an environmental staff scientist for the Restoration & Resilience team and a GIS analyst, combines her passion for environmental research with the power of geospatial data to support sustainable projects that enhance ecosystems and communities alike. GIS is a powerful technology used to study, analyze and visualize geospatial data. In Tara’s role at Princeton Hydro, GIS serves as both a creative and analytical tool, enabling her to generate and explore detailed maps of environmental conditions at project sites, such as vegetation, soils, topography, and water bodies. This process aids in identifying restoration needs, addressing challenges, and developing innovative solutions. Let’s embark on a journey through a typical day in Tara’s role and uncover how her expertise helps shape Princeton Hydro’s environmental restoration projects. Diving Into Data Tara usually starts her day in the office, preparing to analyze data for a particular project. Using GIS software like ArcGIS, she examines historical and current imagery of the site, overlays habitat features, and maps property boundaries. These analyses help Tara and the project team understand the site’s existing conditions, such as watershed boundaries and the presence of threatened or endangered species. “GIS allows us to study locations remotely, uncover patterns and features that might not be obvious on the ground, and understand how a place interacts with its surrounding environment,” Tara explains. “By incorporating extensive environmental data from local, state, and national resources, collected by both public and private organizations, I can gain a comprehensive view of a project site before we even set foot in the field.” From calculating the impacts of a proposed restoration project to mapping flood conditions under various climate scenarios, Tara’s work ensures that Princeton Hydro’s environmental solutions are informed by robust spatial data and cutting-edge technology. One project Tara is especially proud of is Princeton Hydro’s contribution to the Trenton Vulnerability Assessment, part of the Resilient NJ initiative administered by the NJDEP Bureau of Climate Resilience Planning. “We modeled flooding and urban heat islands based on current data and future projections of climate change, and created a mapping tool that overlaid hazard areas with Trenton’s critical facilities, community assets, cultural and ecological resources, and vulnerable populations,” she shares. Tara had the opportunity to present this data to Trenton residents, who shared their questions and ideas for solutions that the City incorporated into its climate planning efforts. “It was a great way to engage with our local Trenton community, get in-person feedback on our maps, and see the potential that GIS and environmental data have in informing social conversations,” Tara adds. Delineating a Watershed Today, Tara is focused on defining the boundaries of a watershed surrounding a small lake. In this video, she walks us through her step-by-step process for watershed delineation: [embed]https://youtu.be/qPi_FvJRGcQ[/embed] Collaborating Across Teams Collaboration is a key part of Tara’s role. On a typical day, she meets with Princeton Hydro’s regulatory team to discuss GIS findings that inform project permitting and compliance. These partnerships enhance her work, ensuring that data analyses align with project goals and regulatory standards. Tara also communicates her findings to clients and stakeholders who may not have technical GIS backgrounds. She uses intuitive maps, symbols, and colors, like blue for water and green for forests, to help stakeholders understand complex concepts at a glance. “Maps are a powerful thing,” Tara says. “They can bring people up to speed quickly and convey information in a way that words alone cannot.” When maps become more intricate, Tara incorporates supplementary visuals, such as tables and graphs, to provide additional clarity. Her ability to bridge technical expertise with accessible communication is crucial for guiding clients through project decisions. Fieldwork and Fresh Air Although much of her work is office-based, Tara occasionally heads out into the field to collect data or monitor project sites. Equipped with GPS tools and field notebooks, she assesses topography, vegetation, and other site-specific details that feed back into her GIS analyses. “Fieldwork provides a fresh perspective,” Tara notes. “It’s a great opportunity to see how projects are implemented and to observe how the environment evolves over time.” Whether delineating watersheds or monitoring post-construction conditions, these outings connect Tara’s technical work to the tangible landscapes she aims to restore. Overcoming Challenges with Innovation and Care Tara thrives on finding innovative solutions to challenges in her work, such as optimizing software processes and addressing gaps in available data. Her meticulous organization of databases, attention to detail, and commitment to accuracy ensure that her outputs are both reliable and impactful. When data is limited, Tara ensures transparency by clearly communicating any uncertainties, fostering trust and confidence in her analyses. Tara also approaches her work with a strong ethical lens, carefully considering the implications of GIS analyses on communities and ecosystems. “When you look at a map of a stream, lake, wetland, or forest in an urban area, it’s important to notice the houses, schools, businesses, parks, and other features that surround them,” Tara explains. “Our projects impact both the environment and people. GIS helps us examine a large area and assess our impact so we can minimize any temporary or permanent effects, both legally and ethically.” She notes that GIS can even identify already disturbed areas for construction access, helping preserve healthier habitats. Continued Inspiration Tara’s love for maps dates back to her childhood, when she was captivated by the intricate, hand-drawn maps in fantasy novels. Her fascination grew through exploring Google Earth, imagining future travels, and observing how geography shapes civilizations. This passion now drives her professional journey, where she uses GIS to merge her analytical skills with creativity. “I’ve always been a visual learner, so I find something grounding about orienting yourself on a map,” Tara shares. When she’s not working, Tara enjoys wildlife photography hikes, baking experiments, and writing music for her ukulele—a testament to her creativity both inside and outside the office. For Tara, GIS is more than a tool; it’s a gateway to understanding and addressing environmental challenges. Her work at Princeton Hydro highlights the versatility of GIS in projects ranging from wetland restoration to climate change resilience. Reflecting on her role, Tara says, “What I love most about GIS is its ability to bring environmental stories to life, helping people connect with the places they care about in a meaningful way.” [gallery link="none" ids="16713,16712,16711"] Through her dedication and expertise, Tara embodies the spirit of innovation and environmental stewardship that defines Princeton Hydro’s mission. Princeton Hydro’s multidisciplinary team combines unparalleled expertise with innovative geospatial technology to deliver integrated ecological and engineering solutions. From comprehensive assessments and sustainable design to implementation and community engagement, we are committed to addressing complex environmental challenges. Our team’s proven capabilities in natural resource management, water resources engineering, and geotechnical design, enhanced by in-house GIS expertise, enable us to provide tailored solutions that achieve measurable results.

In February, we published a blog highlighting Geoffrey's ongoing collaboration in Portugal and his October 2024 visit to key restoration sites, showcasing how barrier removal is addressing river fragmentation and creating a blueprint for future efforts.
We collaborated with the Bucks County Conservation District and Bucks County Planning Commission to launch the Lake Luxembourg Restoration StoryMap, an interactive tool that chronicles the decade-long effort to restore Lake Luxembourg’s Conservation Pool. This dynamic resource combines maps, multimedia, and storytelling to make restoration details accessible to the public. Working with Rutgers University’s Climate Change Resource Center and The Nature Conservancy, we contributed technical expertise to the New Jersey Nature-Based Solutions: Planning, Implementation, and Monitoring Reference Guide. This comprehensive guide offers science-based strategies, case studies, and funding resources to help communities implement nature-based solutions statewide. In partnership with the Borough of Harveys Lake, we developed a ArcGIS StoryMap that chronicles the community’s long-standing commitment to water quality, showcases a pilot project aimed at reducing stormwater nutrient pollution, and connects local efforts to broader Chesapeake Bay watershed health. And, for the Lower Makefield Township Environmental Advisory Council, Geoffrey M. Goll, PE, developed a Rain Gardens 101 step-by-step tutorial on designing and building rain gardens. The recorded presentation, now available to the public, provides practical tips and visuals to help homeowners improve stormwater management and support pollinator habitats.
We strengthened partnerships and advanced critical conversations through a year of dynamic engagement. From technical conferences to community events, our team shared expertise, fostered collaboration, and inspired action on climate resilience, water quality, and ecosystem restoration.

Welcome to our latest installment of the “A Day in the Life” blog series. Today, we delve into the fascinating world of Geographic Information Systems (GIS) analysis through the eyes of Tara Srinivasan. Tara, an environmental staff scientist for the Restoration & Resilience team and a GIS analyst, combines her passion for environmental research with the power of geospatial data to support sustainable projects that enhance ecosystems and communities alike.
GIS is a powerful technology used to study, analyze and visualize geospatial data. In Tara’s role at Princeton Hydro, GIS serves as both a creative and analytical tool, enabling her to generate and explore detailed maps of environmental conditions at project sites, such as vegetation, soils, topography, and water bodies. This process aids in identifying restoration needs, addressing challenges, and developing innovative solutions.
Let’s embark on a journey through a typical day in Tara’s role and uncover how her expertise helps shape Princeton Hydro’s environmental restoration projects.
Tara usually starts her day in the office, preparing to analyze data for a particular project. Using GIS software like ArcGIS, she examines historical and current imagery of the site, overlays habitat features, and maps property boundaries. These analyses help Tara and the project team understand the site’s existing conditions, such as watershed boundaries and the presence of threatened or endangered species.
“GIS allows us to study locations remotely, uncover patterns and features that might not be obvious on the ground, and understand how a place interacts with its surrounding environment,” Tara explains. “By incorporating extensive environmental data from local, state, and national resources, collected by both public and private organizations, I can gain a comprehensive view of a project site before we even set foot in the field.”
From calculating the impacts of a proposed restoration project to mapping flood conditions under various climate scenarios, Tara’s work ensures that Princeton Hydro’s environmental solutions are informed by robust spatial data and cutting-edge technology.
One project Tara is especially proud of is Princeton Hydro’s contribution to the Trenton Vulnerability Assessment, part of the Resilient NJ initiative administered by the NJDEP Bureau of Climate Resilience Planning. “We modeled flooding and urban heat islands based on current data and future projections of climate change, and created a mapping tool that overlaid hazard areas with Trenton’s critical facilities, community assets, cultural and ecological resources, and vulnerable populations,” she shares. Tara had the opportunity to present this data to Trenton residents, who shared their questions and ideas for solutions that the City incorporated into its climate planning efforts. “It was a great way to engage with our local Trenton community, get in-person feedback on our maps, and see the potential that GIS and environmental data have in informing social conversations,” Tara adds.
Today, Tara is focused on defining the boundaries of a watershed surrounding a small lake. In this video, she walks us through her step-by-step process for watershed delineation:
Collaboration is a key part of Tara’s role. On a typical day, she meets with Princeton Hydro’s regulatory team to discuss GIS findings that inform project permitting and compliance. These partnerships enhance her work, ensuring that data analyses align with project goals and regulatory standards.
Tara also communicates her findings to clients and stakeholders who may not have technical GIS backgrounds. She uses intuitive maps, symbols, and colors, like blue for water and green for forests, to help stakeholders understand complex concepts at a glance. “Maps are a powerful thing,” Tara says. “They can bring people up to speed quickly and convey information in a way that words alone cannot.”
When maps become more intricate, Tara incorporates supplementary visuals, such as tables and graphs, to provide additional clarity. Her ability to bridge technical expertise with accessible communication is crucial for guiding clients through project decisions.
Although much of her work is office-based, Tara occasionally heads out into the field to collect data or monitor project sites. Equipped with GPS tools and field notebooks, she assesses topography, vegetation, and other site-specific details that feed back into her GIS analyses.
“Fieldwork provides a fresh perspective,” Tara notes. “It’s a great opportunity to see how projects are implemented and to observe how the environment evolves over time.”
Whether delineating watersheds or monitoring post-construction conditions, these outings connect Tara’s technical work to the tangible landscapes she aims to restore.
Tara thrives on finding innovative solutions to challenges in her work, such as optimizing software processes and addressing gaps in available data. Her meticulous organization of databases, attention to detail, and commitment to accuracy ensure that her outputs are both reliable and impactful. When data is limited, Tara ensures transparency by clearly communicating any uncertainties, fostering trust and confidence in her analyses.
Tara also approaches her work with a strong ethical lens, carefully considering the implications of GIS analyses on communities and ecosystems. “When you look at a map of a stream, lake, wetland, or forest in an urban area, it’s important to notice the houses, schools, businesses, parks, and other features that surround them,” Tara explains. “Our projects impact both the environment and people. GIS helps us examine a large area and assess our impact so we can minimize any temporary or permanent effects, both legally and ethically.” She notes that GIS can even identify already disturbed areas for construction access, helping preserve healthier habitats.
Tara’s love for maps dates back to her childhood, when she was captivated by the intricate, hand-drawn maps in fantasy novels. Her fascination grew through exploring Google Earth, imagining future travels, and observing how geography shapes civilizations. This passion now drives her professional journey, where she uses GIS to merge her analytical skills with creativity. “I’ve always been a visual learner, so I find something grounding about orienting yourself on a map,” Tara shares.
When she’s not working, Tara enjoys wildlife photography hikes, baking experiments, and writing music for her ukulele—a testament to her creativity both inside and outside the office.
For Tara, GIS is more than a tool; it’s a gateway to understanding and addressing environmental challenges. Her work at Princeton Hydro highlights the versatility of GIS in projects ranging from wetland restoration to climate change resilience. Reflecting on her role, Tara says, “What I love most about GIS is its ability to bring environmental stories to life, helping people connect with the places they care about in a meaningful way.”
Through her dedication and expertise, Tara embodies the spirit of innovation and environmental stewardship that defines Princeton Hydro’s mission.
Princeton Hydro’s multidisciplinary team combines unparalleled expertise with innovative geospatial technology to deliver integrated ecological and engineering solutions.

Here at Princeton Hydro, our team members are committed to learning new technologies, staying ahead of regulatory changes, expanding their knowledge, and earning professional certifications in order to better service our clients and the public.
Today, we are proud to put the spotlight on three team members who recently achieved new professional certifications from the Maryland Department of Natural Resources (MDNR).
Environmental Scientist Duncan Simpson, PWS, earned his Maryland Biological Stream Survey (MBSS) Fish Crew Leader certification. He is the only person to have earned this prestigious certification in 2020. He also successfully completed the MBSS Physical Habitat Assessment.
Staff Scientists Ivy Babson and Jesse Smith passed the written MBSS Benthic Macroinvertebrate Sampling Certification test, and successfully completed the related field audit.
The MBSS program was started by the Maryland Department of Natural Resources in 1993 in order to improve consistency among all individuals in Maryland using MBSS habitat assessment protocols so that habitat data are comparable. The MBSS was Maryland's first probability-based or random design stream sampling program intended to provide unbiased estimates of stream conditions with known precision at various spatial scales ranging from large 6-digit river basins and medium-sized 8-digit watersheds to the entire state. This program is a cost-effective and efficient way to characterize Maryland's 10,000+ miles of freshwater streams.
Duncan attended the Fish Crew Leader and Physical Habitat Assessment certification trainings, which were held virtually due to COVID-19. Following the trainings, he successfully passed the required written exams and field audits.
For the habitat assessment field audit, Duncan had to complete an assessment and arrive at the same conclusions as the MBSS experts. He assessed a stream reach for several instream and upland habitat characteristics including audits of bank erosion; bank formation and substrate; stream character; woody debris; max depth; channelization; and riparian vegetation.
The fish crew leader audit required Duncan to lead a team of individuals on a mock fish sampling event during which he was responsible for overseeing that the crew using the MBSS Round Four Sampling Protocol. In order to pass the audit, Duncan had to illustrate his intimate familiarity with every aspect of MBSS sampling and have at least three years of experience with MBSS sampling or with another comparable ecological field sampling effort.
“I first learned about the MBSS certification in 2010 and have been hoping to take the training and earn the certification ever since. I truly admire and respect the scientific rigor of MBSS, so to be recognized with this prestigious certification is a great milestone in my career and something that I’m very proud of.” - Duncan Simpson
For Staff Scientists Ivy and Jesse, the MBSS Benthic Macroinvertebrate field audit required that they collect kicks/jabs in twenty locations within the stream reach, located within the Elbow Branch in Susquehanna State Park. These twenty kicks/jabs were divided up into different microhabitat types depending on which were most dominant in the reach. The MBSS auditor simultaneously collected the same number of each microhabitat type.
The twenty kicks performed by each sampler were compiled into one sample that was preserved and sent to the Maryland State Labs for analysis. In order to pass the audit, Jesse and Ivy’s Benthic Index of Biotic Integrity (a metric based on the diversity and tolerance of the organisms collected) had to be within one unit of the auditor's. Additionally, their successful audit hinged on having the correct supplies and on decontaminating their gear to prevent the spread of invasive species.
"The training experience with MBSS allowed me to gain a deep appreciation of the role that benthic macroinvertebrates hold in our freshwater ecosystems. I’ve been able to develop a unique skillset to help my, and ultimately others’, understanding of benthic macroinvertebrate species richness and what they indicate in terms of water quality that contribute to the health of these special ecosystems." -Ivy Babson
"I've had an interest in aquatic macroinvertebrates since college, and this training experience with the MBSS helped me further appreciate the process that goes into studying them and the ecosystems in which they live. This certification will allow me further opportunities to work with these organisms in the future, and I look forward to more work in this area." - Jesse Smith
In total, the Maryland Department of Natural Resources offers five certification opportunities in MBSS protocols. The certifications include benthic macroinvertebrate sampling, benthic macroinvertebrate laboratory processing and subsampling, fish crew leader, fish taxonomy, and physical habitat assessment. In some cases, prerequisite certifications and trainings are required in order to apply and complete the DNR’s MBSS certifications. For example, in order to achieve the benthic macroinvertebrate taxonomy program, a previous Society for Freshwater Science certification is required.
Attendance at MBSS spring and summer trainings is a partial requirement for most of the certifications. Participants must pass written tests and field audits, as well as additional tests and quality assurance procedures. Passing a laboratory audit and a written test is also required for the benthic macroinvertebrate laboratory processing and subsampling certification.
Congratulations to Duncan, Ivy, & Jesse!

We're excited to put the spotlight on Princeton Hydro Environmental Scientist Emily Bjorhus and her admirable volunteer work.
As an Environmental Scientist, Emily Bjorhus works on a wide range of projects from flood risk management to wetland mitigation to stream restoration. She specializes in wetland and stream ecology and environmental permitting and compliance. Outside of the office, Emily is an active volunteer with Natural Lands and the Delaware Shorebird Project, working to protect natural resources, promote biodiversity, and protect important species. Emily also volunteers at Franklin Delano Roosevelt High School in Brooklyn, NY teaching Environmental Science students about wetlands. We've put together a snapshot of Emily’s volunteer activities:
Natural Lands is a nonprofit organization that saves open space, cares for nature, and connects people to the outdoors in eastern Pennsylvania and southern New Jersey. Founded in the early 1950s, today nearly five million people live within five miles of lands under Natural Lands’ permanent protection.
As a Force of Nature volunteer with Natural Lands, Emily has been monitoring ~20 nest boxes located in meadow and forest edge habitat at Gwynedd Preserve since 2018. From April through mid-August, Emily and another volunteer visit the sites every 5-7 days to monitor the nest boxes for the types of species using the boxes, nest condition, nest materials, number of eggs laid, number of eggs that hatch, and number of chicks that fledge. Chickadees, wrens, blue birds, and tree swallows are the primary species that nest in the boxes Emily monitors.
When asked what she loves most about this volunteer work, Emily said, “I love watching how the birds build their nest week after week, seeing the eggs multiply and tracking the chicks' growth. I even enjoy dodging dive-bombing tree swallows.”
Delaware Shorebird Project is led by DNREC’s Division of Fish & Wildlife in partnership with the U.S. Fish and Wildlife Service, Delaware Museum of Natural History, British Trust for Ornithology and Wash Wader Ringing Group, with the help of experienced and dedicated volunteers like Emily.
The project monitors the health and status of migratory shorebird populations to collect data that can be applied to the conservation of these birds. The research has resulted in better understanding of the ecology of shorebirds migrating through Delaware Bay, management of the horseshoe crab harvest to sustain the shorebirds’ population, and protection of key shorebird habitat.
Emily participated in a 3-day shorebird monitoring initiative, which included counting the number of shorebirds on the beach, re-sighting birds previously marked with leg flags, participating in bird catches, and weighing and measuring birds from the catches. The data collected helps monitor trends in shorebird abundance, migratory routes, condition and other important biological data.
“It's such a pleasure working with the amazing people that come from all over the world to run and participate in this ambitious study,” said Emily. “The data collected from this program will hopefully aid researchers and policy makers to develop strategies to better protect shorebird habitat in the future.”
Ms. Hannah Goldstein and her Environmental Science students at Franklin Delano Roosevelt High School in Brooklyn, NY welcome Emily as a volunteer guest speaker to teach all about wetlands. The instruction also includes a hands-on session where students collect soil samples to determine if hydric soils are present and identify surrounding trees using a dichotomous key.
“Science is such an important subject matter for kids to be learning for a variety of reasons. Environmental science education in particular encourages thought patterns, which get kids engaged in real-world environmental protection activities,” said Emily. “I really enjoy working with Ms. Goldstein and her students. I hope my presentation inspires the students to learn more about wetlands and become ambassadors of wetland conservation.”
Emily earned her M.S. in Sustainable Engineering at Villanova University and holds a B.S. in Environmental Science from University of Colorado at Boulder. As an Environmental Scientist for Princeton Hydro, she coordinates, leads and assists with state environmental permitting programs and NEPA compliance and documentation, including preparation of Federal and state permit applications, Endangered Species Act 7 consultations, and Federal Energy Regulatory Commission (FERC) environmental review processes. In addition, she conducts a variety of environmental field investigations such as wetland and waterbody delineations.
We’re so proud to have Emily on our team and truly value the work she does inside and outside the office.
We’re excited to announce the hiring of four new team members! The addition of this group of talented individuals strengthens our commitment to delivering exceptional service.

The Resource Institute hosted its 9th Annual Mid-Atlantic Stream Restoration Conference in Baltimore, Maryland, where water resource professionals, researchers, and practitioners come together for three days to share ideas and learn about stream restoration planning, assessment, design, construction, evaluation, and other topical stream issues. The conference, which was themed Building Resilient Streams in the Mid-Atlantic and Northeast regions, included presentations, discussions, exhibits, and pre-conference workshops. Princeton Hydro participated in three presentations on a variety of topics.
Below, we provide a synopsis of each presentation:
The presentation provides a detailed look at the removal of the Martin Dam in Fallston, Maryland, and how project partners were able to drastically expand the footprint of this emergency dam removal to generate enough ecological restoration benefits to adequately fund the dam removal itself.
The Martin Dam was constructed in 1965 as part of USDA’s sustainable farms pond construction initiative, which promoted aquaculture and subsistence fish production on small farms across the region as an income source for agricultural producers. Dam-related impacts included the permanent loss of spring-fed sedge wetlands, ditching of forested floodplain wetlands, pollution from stream bank entrenchment, and thermal impacts to a wild brook trout population downstream.
Overtime, the dam structure began to degrade. With each state and local agency inspection that was conducted, the dam increased in hazard category. In 2016, the Maryland Department of the Environment (MDE) was forced to list the dam as a, “public safety hazard at risk of immanent failure.” The landowner, unable to fund the dam removal, contacted GreenTrust Alliance (GTA), a regional green infrastructure nonprofit organization, for help.
By emphasizing the ecological benefits of restored wetlands and streams above and below the dam as well as the critical public safety hazard faced by residents and motorists downstream, GTA, in partnership with Princeton Hydro and GreenVest, was able to secure restoration funding for the site. The design and permitting was led by Princeton Hydro, and the dam was safely breached as part of restoration construction in January 2019.
In order to explore the use of drone or UAV technology to evaluate the effects of dam removals, the presentation showcases the Columbia Lake Dam removal, the largest dam removal in New Jersey to date.
The Columbia Lake Dam, built in 1909, was 18 feet high, 330 feet long dam, and stretched more than 1.5 miles on the Paulins Kill less than 0.25 miles upstream from its confluence with the Delaware River. As part of The Nature Conservancy’s (TNC) mission to improve the quality of the Paulins Kill, removing this “first blockage” was the cornerstone of the larger mission. Princeton Hydro served as the engineer-of-record, designing and permitting this project. Dam removal activities commenced in 2018 and were finalized in 2019. Its removal opens 10 miles of river for fish migration and improves recreation access, floodplain reconnection, habitat enhancement and higher water quality.
TNC will conduct five years of monitoring, a vitally important component of this project, to determine long-term ecological uplift, short-term positive and negative effects, and to develop data to provide information for future dam removals. And, as a result of the programmable and repeatable nature of drone flight paths, such monitoring will be able to be conducted for years and decades, producing invaluable data for research and future project design.
The presentation reviews the various parameters investigated, the results and significance of the data retrieved, and recommendations for the use of drone technology for future ecosystem restoration projects.
This presentation provides an overview on how to create 3D river models based on geomorphic input to enhance the overall accuracy and quality of a river restoration project.
In river restoration, the proposed geometry of the river channel is the key part of the design. It impacts earthwork, utility conflicts, plan set layout, and many other aspects of the project. In larger projects with reaches measuring thousands of feet and greater, manual grading is extremely time consuming and tedious; and determining the entire implication of the proposed design is difficult to achieve when simply analyzing proposed cross-sections and profiles. To increase efficiency and maintain uniformity throughout the subject reach developing a 3D-surface model of the proposed restoration reduces design time and increases quality. AutoCAD Civil 3D can be used to convert the proposed profiles and cross-sections from a geomorphic design into a 3D surface of the river corridor.
The presentation goes through the key steps that need to be taken and strategic questions that need to be asked when modeling 3D rivers in AutoCAD along with important tips and reminders.

The Watershed Institute held its 3rd Annual New Jersey Watershed Conference, an educational event that aims to advance knowledge and communications on issues related to water quality and quantity across the state. The event included a variety of presentations from local experts on watershed management, stormwater, and problems and solutions related to the health of New Jersey's watersheds.
During the conference, Princeton Hydro’s Marketing Coordinator Kelsey Mattison, a St. Lawrence University graduate with a degree in English and environmental studies, lead a workshop that explored binaries in environmental thought and how to break through those limiting thought processes in order to advance a more productive and shared understanding of our natural world.
The presentation, titled “Flipping the Script on American Environmental Thought,” discussed how black-and-white thought processes (a.k.a. binaries) cause us to view issues as one or the other, leaving little to no room for the possibility of blending the two.
Historically, American thought has viewed environmental issues through a binary lens: either we favor human society, or we favor the environment, and this juxtaposition has rarely allowed for integration between the two perspectives.
Take, for example, the two concepts of preservation and conservation toted by John Muir and Gifford Pinchot, respectively. Muir’s concept of preservation argued that humans should set land aside to leave untouched to preserve its natural beauty, while Pinchot’s concept of conservation advocated for a responsible use of the land’s resources. Both are forms of environmental advocacy, but neither leave much room to combine the two ideas, ultimately creating a black and white binary surrounding human responsibility to the planet. This makes it difficult to then make any compromise on issues related to managing or utilizing our natural resources.
The workshop also explored answers to the important question of: “How do we flip the script to be more inclusive?” Participants discussed ideas around utilizing Values-Based Communication in order to connect with people from different groups/with different values. A few of the communication strategies Kelsey presented, include:
When groups are telling such different narratives, it can be hard to see that their goals might actually be completely in line. By first identifying what each group's priorities are, we can better understand their needs in order to help fulfill them. This allows people with seemingly conflicting beliefs to work towards a common goal.
Generally, people default to thinking there are only two sides to an issue, but no conflict is ever truly just one thing or the other. Even if there are overtly two options, the issue is always more complex. When resolving conflict, it’s almost always possible to find at least one thing the two sides have in common.
The New Jersey Watershed Conference, of which Princeton Hydro was a sponsor and exhibitor, also included presentations on topics ranging from urban flooding to microplastics in our waterways to green infrastructure. Dr. Fred Lubnow, Princeton Hydro's Director of Aquatic Programs, presented on the "Causes and Impacts of Harmful Algal Blooms." To view the complete agenda, go here.
Princeton Hydro is a proud supporter of The Watershed Institute, a nonprofit organization comprised of policy advocates, scientists, land and water stewards, naturalists, and educators.
