Model My Watershed

800 532 Stroud Water Research Center

Stroud Water Research Center continues to maintain and update the Model My Watershed® web application. Updates for 2021–2022 include adding historic and more current layers of land use data and a higher resolution stream network map for the contiguous 48 states and updating the underlying software version to ensure future functionality.

(Project details may change over the lifespan of a project. The project description listed here is from the annual report of the most recent project year.)

Funded by: Stroud Water Research Center, William Penn Foundation, Pa. Department of Environmental Protection

Principal Investigators: David B. Arscott and Steven C. Kerlin

Collaborators: Anthony Aufdenkampe (LimnoTech); Lin Perez, Barry Evans, and Michael Campagna (Academy of Natural Sciences of Drexel); Robert Cheetham (Azavea, Inc.).

2014 Through 2020

This project expands the Model My Watershed® application to the entire Delaware River Basin and supports restoration efforts funded by the William Penn Foundation. This application will provide higher-resolution modeling for developing effective restoration plans in targeted watersheds.

2009 Through 2013

Stroud Water Research Center educators and scientists launched Model My Watershed, an innovative, three-year program to develop, test, and disseminate a watershed-modeling tool set for Philadelphia-area secondary schools. The goal of the program is to engage and excite students about the diverse science, technology, engineering, and math (STEM) careers needed to address environmental issues. Using an interactive, hydrologic modeling tool set, students make real-world decisions based on real scientific data and models and learn to predict how environmental changes in their watersheds affect the hydrologic cycle.
