Implications of Land Use, Cover, and Management Change in the Chesapeake Bay Watershed
A trends analysis of urban growth in the Chesapeake Bay watershed. Dark orange-red areas are forecasted to experience highest urban growth by 2025.
The Chesapeake Bay Program Partners rely on land-use/cover data to: 1) calibrate the HSPF Phase 5 Watershed Model; 2) parameterize the USGS SPARROW model; 3) identify sources of nutrients and sediments; 4) inform development of state Watershed Implementation Plans; 5) assess the vulnerability of habitats to urban development; and 6) monitor change in impervious cover, forests, and riparian vegetation. Through monitoring land use and land cover change in the Chesapeake Bay watershed, USGS will provide comparable and consistent land cover data for the Bay watershed every 5-yrs, develop high-resolution land-use/cover datasets to support small watershed studies, monitor regional changes in impervious surfaces and riparian forest buffers with high levels of precision, and develop and disseminate semi-automated mapping tools for citizen mapping and monitoring of land-use/cover change and to support land change science education.
