California's Exposure to Volcanic Hazards
A geonarrative summary of the USGS report that provides a broad perspective on California’s exposure to volcanic hazards. By integrating volcanic hazard information with geospatial data on populations, infrastructure, and resources, the results provide estimates of impacts to people and our environment if an eruption were to occur.
Public-Supply Well Water Quality Results: Inorganic Data and Trends, 1974 - 2014 (California GAMA-PBP)
The GAMA-PBP Public-Supply Well Results data viewer allows the user to visualize and download California water-quality data and trends for1974 - 2014. Groundwater-quality data for 38 inorganic constituents are captured and can be downloaded for individual sites or by grid cell.
Louisiana Flood Alert Map
Developed by Lower Mississippi-Gulf scientists, these visual flood warning maps empower citizens, federal, state, and local partners to understand flood risks in Louisiana.
Story Map: Avian Influenza in the United States
This story map explores the role USGS scientists play in understanding the risks presented by avian influenza, and how their work is being used to predict areas of transmission risk.
Anza Land Use Comparison (1934 - 2005)
Compares Anza Valley, CA land use data within the USGS study boundaries for 5 time periods between 1934 and 2005.
Anza Hydrologic Data
A portal for easy access to USGS data collected during hydrogeologic research projects in Anza Valley, CA
Coastal Change at Fire Island
This geonarrative features research used to predict how Fire Island beaches change in response to storms and how they may subsequently recover in the year following a storm event.
2012 SPARROW Models for the Midwest: Total Phosphorus, Total Nitrogen, Suspended Sediment, and Streamflow
2012 SPARROW (SPAtially Referenced Regressions On Watershed attributes) interactive mappers are available for 5 regions of the conterminous U.S. These mappers simulate river streamflow, and nutrient and sediment loads and yields, that would occur under long-term average hydrologic conditions for the time period 1999 through 2014, and source inputs that occurred during or near 2012.
2012 SPARROW Models for the Northeast: Total Phosphorus, Total Nitrogen, Suspended Sediment, and Streamflow
2012 SPARROW (SPAtially Referenced Regressions On Watershed attributes) interactive mappers are available for 5 regions of the conterminous U.S. These mappers simulate river streamflow, and nutrient and sediment loads and yields, that would occur under long-term average hydrologic conditions for the time period 1999 through 2014, and source inputs that occurred during or near 2012.
2012 SPARROW Models for the Pacific: Total Phosphorus, Total Nitrogen, Suspended Sediment, and Streamflow
2012 SPARROW (SPAtially Referenced Regressions On Watershed attributes) interactive mappers are available for 5 regions of the conterminous U.S. These mappers simulate river streamflow, and nutrient and sediment loads and yields, that would occur under long-term average hydrologic conditions for the time period 1999 through 2014, and source inputs that occurred during or near 2012.
2012 SPARROW Models for the Southeast: Total Phosphorus, Total Nitrogen, Suspended Sediment, and Streamflow
2012 SPARROW (SPAtially Referenced Regressions On Watershed attributes) interactive mappers are available for 5 regions of the conterminous U.S. These mappers simulate river streamflow, and nutrient and sediment loads and yields, that would occur under long-term average hydrologic conditions for the time period 1999 through 2014, and source inputs that occurred during or near 2012.
2012 SPARROW Models for the Southwest: Total Phosphorus, Total Nitrogen, Suspended Sediment, and Streamflow
2012 SPARROW (SPAtially Referenced Regressions On Watershed attributes) interactive mappers are available for 5 regions of the conterminous U.S. These mappers simulate river streamflow, and nutrient and sediment loads and yields, that would occur under long-term average hydrologic conditions for the time period 1999 through 2014, and source inputs that occurred during or near 2012.
