Unified Interior Regions

Scientists at the U.S. Geological Survey are closely watching the long, thin barrier islands that comprise the Gulf of Mexico coast of west Florida as Hurricane Ivan approaches. These islands are particularly vulnerable to storm surge and coastal change during hurricanes because of their low elevation. New elevation maps show just how vulnerable.

Streamgages continue to measure new daily record high flows on waterways along the U.S. eastern seaboard as yet another hurricane promises to deliver more rain to parts of the already soggy region. Although flooding in the immediate Richmond area receded quickly earlier this week, the city may receive additional heavy rainfall from Frances in coming days.

Based on airborne laser mapping data acquired in cooperation with National Aeronautics and Space Administration (NASA), scientists at the U.S. Geological Survey (USGS) have estimated the coastal-change impacts that may be caused by Hurricane Frances as it makes landfall on the U.S. south Atlantic coast over the Labor Day weekend.

Manatee populations are growing at healthy rates in two of four regions off Florida’s coast, but may be stalled or declining in the remaining regions, according to a recently released report by the U.S. Geological Survey.

Did you know that from your desk you can monitor the effect of this week’s heavy rains throughout the already saturated mid-Atlantic region? The U.S. Geological Survey’s (USGS) WaterWatch Web site can show you what’s happening to streams in your local area and show you the places most affected by heavy rains expected from these storms.

A new assessment of shoreline change on the Gulf of Mexico, released today by the U.S. Geological Survey, shows that 61 percent of the Gulf Coast shoreline is eroding. Some areas are losing sand more rapidly than others and some areas are actually gaining sand.

America’s rivers and streams are generally suitable for irrigation, supplying drinking water, and home and recreational uses. However, in areas with significant agricultural and urban development, the quality of our nation’s water resources has been degraded by contaminants such as pesticides, nutrients, and gasoline-related compounds.
