Coastal hazards are a widespread challenge that cost millions (and sometimes billions) of dollars in the U.S. every year due to property loss and spending on mitigation measures. Based on the most recent U.S. Census, over 39% of the U.S. population lives in areas that may undergo significant coastal flooding during a 100-year flood event. Additionally, six of the ten most expensive weather-related disasters in U.S. history have been caused by coastal storms.
Flooding is a perennial hazard for rivers and coasts alike. Every year, flooding results in billions of dollars of damage and the loss of dozens to hundreds of lives across the United States. Efforts to mitigate this hazard rely on the work of geoscientists, planners, and communicators to assess and minimize risks, prepare and inform communities, and ensure that lives and livelihoods are prioritized before, during, and after flood events.
On November 14 the House of Representatives passed legislation that would reauthorize the National Flood Insurance Program (NFIP) for five more years, while making several operational changes. According to the Office of Management and Budget, the NFIP is not fiscally sustainable in its present form, and is currently set to expire on December 8.
The U.S. Geological Survey's Water On The Go app provides real-time information on stream flows, lake levels, and rainfall in Texas. The app automatically finds data near your current location (or any chosen location in Texas) for rapid access to water information. Special icons indicate rapidly rising streams and lakes or heavy rain that may pose a flood risk.
Users can click on individual sites for current water levels, a graph of levels in recent days, and links to more data and information about the site.
In anticipation of Hurricane Harvey making landfall on the Gulf Coast, several federal science agencies prepared for the massive storm by monitoring its development and helping direct FEMA's resources to the likely hard-hit areas.
The Delaware Department of Natural Resources and Environmental Control (DNREC) Flood Tool is an interactive map with flood risk information. It is designed to help users make informed decisions about flood risk in specific areas and on specific properties.
