The Sediment Transport Instrumentation Facility at USGS Woods Hole Field Center maintains and deploys oceanographic instrumentation for the study of coastal and ocean circulation and sediment transport.
Current river mechanics research on particle friction angles of fluvial gravels (data files compressed in BenHex, Winzip and Unix) and Grand Canyon Beach evolution (animation requiring Java 1.0) plus digital elevation files (*.hgx and *.zip files).
Sediment from rivers has both beneficial and detrimental effects on ecosystems and human activities around Puget Sound. We explain where the sediment comes from, how it is transported, and the nature of the data that we can use to understand it.
Suspended-sediment concentration data were collected in San Francisco Bay during water year 2000 using optical backscatterance sensors and water samples. This report presents the data-collection methods, data, and calibration plots.
This site is designed to provide information on federal interagency and cooperative developments related to coastal sand and gravel resources and management issues along the Atlantic continental margin.
This publication focuses on the geological framework and sedimentary processes of the Lake Pontchartrain Basin and provides links to interactive tools, regional research, and sediment data in GIS formats for display and analysis.
Topics in Coastal and Marine Sciences provides background science materials, definitions, and links to give a common context for users from a variety of backgrounds. Coastal erosion was chosen as the first topic.
We mapped substantial migration of the river channel between the City of Winslow and the Navajo Nation community of Leupp; in a human lifetime the river has moved more than a mile across its valley floor.
Project of the Gulf of Mexico Integrated Science program that evaluates the transport and sedimentation of contaminates through the Mississippi River and Atchafalaya River delta to the near-shore Gulf of Mexico. Includes aerial photographs.
This web site is an outgrowth of an agreement between the USGS and the New England Aquarium, designed to summarize and make available results of scientific research. It will also present educational material of interest to wide audiences.
Overview with links to studies on the effects of human activity on the San Francisco estuary with loss of historic fresh and saltwater tidal marshes reducing habitats, introducing contaminants in waste, and creating dredging problems.
Brief review of studies with sidescan sonar on sediment in the Grand Canyon as part of research on the changes brought about by the Glen Canyon Dam and the results gathered from a 1996-controlled flood experiment with links to related information.
Description of research studies of the Lake Roosavelt-Upper Columbia area on contaminants and effects on environmental health with links to publications and products, partners, related links, project summaries, and contacts.
We combine long-term records from aerial photographs, detailed mapping using survey-grade GPS, and ground-based lidar with meteorological monitoring. Sand dune migration rates are currently about 35 meters per year.
Webpage based on USGS Open File Report 98-139 links to information on the San Francisco Bay estuary to study dredge disposal effects, fish habitats, sediment transport, rock pinnacles and navigation, and consequences of a large oil spill.
The National Assessment of Coastal Change Hazards is a multi-year undertaking to identify and quantify the vulnerability of U.S. shorelines to coastal change hazards such as the effects of severe storms, sea-level rise, and shoreline erosion and retreat.
Homepage for description of the National Stream Quality Network (NASQAN), a long-term program monitoring the concentrations and flux of sediment and chemicals in the Nation's largest rivers (Mississippi, Columbia, Colorado, Rio Grande, and Yukon).
Report with preliminary sea floor map displaying submarine rock exposures found along the northern part of Monterey Bay National Marine Sanctuary, extent based on side-scan sonar records, seismic-reflection records, and underwater video.
Study addresses questions and concerns related to limited sand resources along the Louisiana shelf and their implications to long-term relative sea-level rise and storm impacts, using newly acquired geophysical and vibracore data.
USGS project to understand coastal evolution and modern beach behavior; to identify and model the physical processes affecting coastal ocean circulation and sediment transport; and to identify sediment sources and construct a regional sediment budget.
Description of Long Island Sound projects and links to research topics, data, publications, photos, and technology on sediment transport, sea floor mapping, contaminant sampling, sediment texture, and environmental issues.
Lead page for detailed United States surface water information with links to real-time and historic streamflow data, suspended sediment data, USGS programs and facilities, publications, techniques, and featured news releases.
Summary of a circular on USGS environmental research and Chesapeake Bay with links to full document. Includes discussion of the problems of the estuary, restoration efforts, water quality, and effects on ecosystem.
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.
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.
