Interactive Maps

Obique photos offer a unique perspective of the coast. Features such as beach erosion or accretion, dune erosion and overwash can all be clearly characterized in this imagery. It also documents coastal infrastructure, as well as the damage that infrastructure may incur as the result of an impacting hurricane.

Maximum likelihood logistic regression is used to estimate drought probabilities for selected Virginia rivers and streams 5 to 11 months in advance. Hydrologic drought streamflow probabilities for summer months are provided as functions of streamflows during the previous winter months. This application allows the display and query of these drought streamflow probabilities for Virginia streams.

In 1998 the Upper Midwest Environmental Sciences Center (UMESC) began aquiring digital orthophoto quadrangles (DOQ) for the Upper Mississippi River floodplain to georeference the center's aerial photography and land cover/use data. As these data become available, the files are compressed and placed online so others can also use them.

The Virginia Water-Monitoring-Sites Mapper is an interactive map of Virginia water monitoring-site locations from the USGS Water Data for the Nation. It provides access to surface water, groundwater, and water quality monitoring data for active sites.

The West Virginia Water-Monitoring-Sites Mapper is an interactive map of West Virginia water monitoring-site locations from the USGS Water Data for the Nation. It provides access to surface water, groundwater, and water quality monitoring data for active sites.

Scientists refined the existing national-scale "De facto Reuse Incidence in our Nation's Consumable Supply" (DRINCS) model for the Shenandoah River watershed. The model, complemented by field measurements, provides a screening tool to understand human and wildlife exposure to toxicants and pathogens associated with the incidental reuse of treated wastewater in the watershed.
