Describes and provides links to USGS research in the location of the estuary and coast of Long Island, New York, to map the sea floor and to study sediment transport, contaminants, and sand resources and coastal vulnerability.
Outlines processes that control the release of metals and acidic waters from inactive mines and mineralized areas, the transport of metals and acidic waters to streams, and the fate and effect of metals and acidity on downstream ecosystems.
Program to measure streamflow stage and discharge at four sites in the Upper Wallkill River Valley's Black Dirt Region and determine Total Suspended Solids (TSS) concentration data and estimate loads of TSS and sources of contaminants.
Tripod-mounted lidar makes it inexpensive and efficient to measure and map geographic features that change with time, such as sand dunes and erosional features, and soil microtopography.
Links to major databases on USGS real-time and historic time period data for water quality, atmospheric deposition, streamflow, and suspended sediments and links to related databases of other agencies.
Explains how mathematical simulations of watershed properties can help us understand the likely behavior of the water systems, putting the choices available to people in better perspective.
