Quantifying Floodplain Ecological Processes and Ecosystem Services in the Delaware River Watershed

Floodplain and wetland areas provide critical ecosystem services to local and downstream communities by retaining sediments, nutrients, and floodwaters. The loss of floodplain functionality due to land use conversion and degradation reduces the provisioning of these services. Assessing, quantifying, and valuing floodplain ecosystem services provide a framework to estimate how floodplain...

U.S. Geological Survey (USGS) Science Summary—New digital map documents surficial-aquifer thickness in the Delmarva Peninsula, Maryland and Delaware: Helping to understand the role of groundwater in delivering nitrogen to Chesapeake Bay

Nitrate, the major source of nitrogen in streams of the Eastern Shore of Chesapeake Bay and the wider Delmarva Peninsula, is transported primarily in groundwater through the unconfined surficial aquifer. Understanding the subsurface processes that affect nitrate transport in this area has been hampered by a lack of regional information on the thickness of this aquifer.

Chesapeake Bay Activities Bibliography

The USGS has published reports and journal articles on a large number of topics related to the Chesapeake Bay and its watershed. Some recent reports are online. Findings from the publications are used by Chesapeake Bay Program resource managers and policy makers to make science-based decisions for ecosystem conservation and restoration. USGS Chesapeake Bay science information is also critical...

Enhanced hydrologic and geomorphic monitoring in Ten Mile Creek, Montgomery County, Maryland

Ten Mile Creek is a small, predominantly agricultural and forested watershed located to the west of Clarksburg, Maryland, in an area that has experienced land-use change and urban development over the past decade. Additional development extending into the Ten Mile Creek watershed is planned over the next several years.

This planned development in the Ten Mile Creek watershed presents an...

Seabird Research Program

The Seabird Research Program at PWRC is focused on studying the ecology of species present across the Atlantic Coast. This program was a natural progression of PWRC's historic work studying the coastal ecology of wildlife in and around the Chesapeake Bay. We now focus on the three key areas on a variety of species: physiology, avoided bycatch, and movement ecology.

Shoreline Changes and Impacts to Natural Resources in Chesapeake Bay

The Challenge: Climate change and sea level rise are expected to affect many miles of shoreline in the Chesapeake Bay and elsewhere along the Atlantic Coast in the coming years. In this scenario, federal and state agencies need to make more detailed assessments of how different watersheds and shoreline types might influence an array of ecosystem functions and components. Recently, most states...

Geomorphic Responses to Stream Channel Restoration at Minebank Run, Baltimore County, Maryland

Urban streams frequently undergo severe incision and erosion due to flashy streamflows caused by impervious surfaces in the watershed. The study was designed to investigate the hydrodynamics and geomorphology of a selected reach of Minebank Run before and after stream restoration, in order to determine the effect that stream restoration had on sediment processes in the stream.

Surge, Wave, and Tide Hydrologic (SWaTH) Network in Maryland, Delaware, and the District of Columbia

Many U.S. Geological Survey Water Science Centers have responsibilities for coastal regions within their mission areas. The integrated Surge, Wave, and Tide Hydrologic (SWaTH) Network has been developed in the wake of Hurricane Sandy to support model development and verification for coastal regions, detection of hydrologic trends, and early warning of hydrologic hazards in the northeast from...
