We conduct post-fire debris-flow hazard assessments for select fires in the Western U.S. We use geospatial data related to basin morphometry, burn severity, soil properties, and rainfall characteristics to estimate the probability and volume of debris flows that may occur in response to a design storm.

Maps, reports, and digital data available as shape files, images, or grids in GIS format, that depict the bathymetry, surficial geology, or subsurface structure of submerged areas at various scales. The information addresses scientific and management issues that are important to the environment and economy of coastal communities and the Nation.

Grand Lake Data Viewer - View topographic and bathymetric contour data and simulate Grand Lake inundation areas for selected water-surface elevations.

Natural resources and environmental data, including orthoimagery, hydrologic, and cartographic data.

Find out how much rain has fallen—how many gallons have come down from the skies onto your roof, yard, block, or town.

Access to regional web cameras located in the desert southwest and arctic Alaska. Desert cameras capture and document regional climate variability with a specific focus on local and regional dust emission and transport. The artic Alaska cameras capture and document regional climate variability with a specific focus on snow cover and permafrost feature evolution.

The SPARROW (SPAtially Referenced Regression on Watershed attributes) model was used to simulate annual phosphorus loads and concentrations in unmonitored stream reaches in California, U.S., and portions of Nevada and Oregon.

The Texas Geology Web Map Viewer is the third generation in a series of Texas geologic mapping products which is intended to empower and expose surface geology details to a broad range of diverse users interested in exploring the geology of the State of Texas.  Key features incude clear navigational controls, location search, and an identify tool to retrieve detailed formation data.

Delineate custom drainage basins, compute basin characteristics, and estimate streamflow statistics.

U.S. Water Use from 1950-2015 is an interactive map viewer used to visualize water use by region and date for U.S. freshwater withdrawals, 1950-present (created by USGS VIZLAB).

On March 27, 1964 the largest recorded earthquake in U.S. history struck southcentral Alaska.  Click on the photos or the numbers to take a tour.

The U.S. Geological Survey applied the SPARROW model to assess the loads delivered in 2002 for estuaries and coastal waters along the Atlantic Ocean and eastern Gulf of Mexico.
