Chesapeake Bay Activities

The Chesapeake Bay is our Nation’s largest estuary and provides over $100 billion in annual economic value. The USGS works with Federal, State, local, and academic partners to provide research and monitoring and to communicate results to inform management for the Chesapeake and other important landscapes across the Nation.

Mapping stream and floodplain geomorphometry with the Floodplain and Channel Evaluation Tool

Broad-scale mapping of stream channel and floodplain geomorphic metrics is critical to improve the understanding of geomorphic change, biogeochemical processes, riverine habitat quality, and opportunities for management intervention. The Floodplain and Channel Evaluation Tool (FACET) was developed to provide an open-source tool for automated processing of digital elevation models (DEMs) to generat

Societal benefits of floodplains in the Chesapeake Bay and Delaware River watersheds: Sediment, nutrient, and flood regulation ecosystem services

Floodplains provide critical ecosystem services to people by regulating floodwaters and retaining sediments and nutrients. Geospatial analyses, field data collection, and modeling were integrated to quantify a portfolio of services that floodplains provide to downstream communities within the Chesapeake Bay and Delaware River watersheds. The portfolio of services included floodplain sediment and n

The Chesapeake Bay Land Change Model (CBLCM): Simulating future land use scenarios and potential impacts on water quality

The Chesapeake Bay Land Change Model (CBLCM) is an open-source pseudo-cellular automata land change model tailored for loose coupling with watershed models. The CBLCM simulates infill development, residential and commercial development, natural land and agricultural land conversion, and growth served by sewer or septic wastewater treatment. The CBLCM is unique among land change models by simulatin

USGS Publications Summarize Water-Quality Trends and Drivers in Urban Streams After 10 Years of Monitoring in Fairfax County, Virginia

Issue: Degraded water quality and ecology in urban streams has been widely documented, but explanations of changing conditions over time are often unavailable. A 15-year collaborative urban stream monitoring effort between the Fairfax County Stormwater Planning Division and the U.S. Geological Survey (USGS) is ongoing and has begun to shed light on this complex issue. In a new USGS report by...

Floodplains provide millions of dollars in benefits every year to people in the Chesapeake Bay and Delaware River watersheds

Issue: Floodplains provide important services to people by retaining sediments, nutrients, and floodwaters, thereby improving water quality and reducing flooding impacts. Having information on how the monetary benefit that floodplains provide varies across the Chesapeake Bay and Delaware River watersheds helps resource managers describe the benefits that floodplains provide in their current state...

Pennsylvania and the Chesapeake Bay Watershed

USGS provides monitoring, analysis, modeling and research on streams and water quality to better understand the fate and transport of nutrients and sediment to the Susquehanna and other rivers, and their tributaries, and eventually to the Chesapeake Bay. Additional research focuses on emerging contaminants and other stressors that effect human and aquatic life in the watershed and estuary.
