Land-Use Monitoring and Forecasting

Efforts are underway to protect the rich array of lands and habitat across the Bay watershed for fish, wildlife, and people. However, new high-resolution data show an alarming loss of forests and other vital lands because of development. The USGS is leading analyses of the enhanced land-change data, and forecasting scenarios of future use, to inform land-protection and local-planning decisions.

New high-resolution, land-use and change data improves decision-making in the Chesapeake Bay watershed

Issue Informing restoration across the nearly 64,000 square miles of the Chesapeake Bay watershed is an enormous challenge that requires detailed and accessible landscape data. Among the most pressing challenges being addressed by the Chesapeake Bay Program (CBP) partnership are: → Water pollution from agriculture and animal waste, → Conversion of critical habitat like forest and marshes for new...

Altered flow affects the biological health of streams in the Chesapeake Bay watershed

Issue: The natural cycle of water flow, known as the flow regime, is one of the primary habitat conditions needed for healthy biological communities in streams. However, human activities have drastically altered the natural flow regime of most of the world’s rivers and streams, including those in the Chesapeake watershed, which has resulted in changes not only to the natural habitat but also...

New dataset available on stream and floodplain geometry to inform restoration decisions

Issue: The need for stream mapping The physical shape of streams and floodplains can provide information about how water, sediment, and other matter moves through the landscape. Streams can have deep channels (tall streambanks) disconnected from the floodplain or wide shallow channels that easily spill over the banks into the floodplain during high flows. Mapping where streams fall along this...

Projecting stream conditions under future land-use and climate scenarios

Issue: Global change, particularly changes in land use and climate, is dramatically altering stream conditions throughout the world. Healthy streams are important for freshwater fisheries, wildlife, and public recreation. The Chesapeake Bay Program (CBP) has a goal of improving the health of streams throughout the Chesapeake Bay watershed, which includes an outcome of improving the condition of 10...

Tripod-palooza—USGS Collaborates with Federal, State, and Academic Partners to Support Coastal Resiliency in the Wider Chesapeake Bay Area

In the Chesapeake Bay area, the Virginia and West Virginia Water Science Center is partnering with over a dozen organizations in a pilot project this fall, resulting in the establishment of a baseline reference for an ongoing effort in monitoring coastal subsidence.

USGS 3D Elevation Program Supports Science Activities in the Chesapeake Watershed

Increased acquisition of lidar in the Chesapeake Watershed The Chesapeake Bay Program has a critical need for enhanced land cover and land-use information to better inform restoration and conservation efforts throughout the watershed. An important component of land information is more detailed land elevation data, which are collected using lidar (light detection and ranging), a remote sensing...

Science Summary—USGS develops novel approach to assess efficiency of stormwater management practices

Issue Urban stormwater runoff is a rapidly increasing source of pollutants to Chesapeake Bay. It contributes on average 16 percent of the nitrogen, 16 percent of the phosphorus, and 25 percent of the sediment load to the bay annually. Urban stormwater best management practices (BMPs) (fig. 1) have been used in an effort to reduce the volume and improve the quality of stormwater runoff entering...
