Prediction of Flooding Now and Into the Future: a geonarrative on coastal storms

The USGS is conducting a comprehensive evaluation of groundwater resources of the Adelaida area. Use this map to explore the hydrogeology of the area, including land use, geology, and USGS hydrologic data by watershed or water management district.

A simulation-based power analysis can be used to estimate the sample sizes needed for a successful monitoring program, but requires technical expertise and sometimes extensive computing resources. We developed a web-based lookup app, called TrendPowerTool.

Alaska's north coast has been home to indigenous communities for centuries. Changing coastlines threaten important infrastructure and historic sites that support indigenous communities. Changing coastlines also can potentially reduce habitat for Arctic wildlife, such as polar bears, shorebirds, and walruses.

This USGS geonarrative (Esri Story Map) summarizes the USGS response and findings after the M6.4 on July 4 and M7.1 on July 6, 2019 in Searles Valley, Southern California, and includes links to USGS research publications and data releases.

The Delaware River supports thriving ecosystems and drinking water for 16 million people. How water is shared, and the quality of that water, has been the focus of decades of inter-state discussion, negotiation, and research. This data visualization story uses streamflow, salinity, and temperature to show how new USGS science and monitoring can inform water management in this age of cooperation.
