Transport of solid particles of unconsolidated rock and mineral fragments, chemical precipitates, or biological materials.
USGS science for the Nation's changing coasts: Shoreline change research [ More info] Explains how and why coasts, beaches, and shorelines change, and how we study these changes.
USGS science for the Nation's changing coasts; Shoreline change assessment [ More info] Shorelines are always changing, yet we use these areas heavily. This shows what we measure and how, to help adapt to changing coastal zones.
USGS studies in the New York Bight [ More info] 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.
Using terrestrial light detection and ranging (lidar) technology for land-surface analysis in the Southwest [ More info] 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.
Wastewater Indicators Shown to Degrade in Streams [ More info] Research findings and examples of application to real problems--the stability of contaminants that indicate human wastewater needs to be considered.
Water-quality information - data [ More info] 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.
Watershed modeling applications in south Texas [ More info] 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.
