U.S. map of real-time streamflow compared to historical values with links to U.S. maps and data of surface water, ground water, precipitation, river conditions and floods and other information on current and past water resources conditions.
Severe flooding occurred in northern Maine from April 28 to May 1, 2008, and damage was extensive in the town. Aroostook County was declared a Federal disaster area. Our flood inundation maps were out of date, so we have updated them; this explains how.
In September of 2009, flooding in parts of Georgia reached levels expected every 500 years. Specific measurements we made and other facts about these disasters described here should help people prepare for floods here and elsewhere.
Annual peak flows have increased at most rivers in Maine during the last century. What effect does this have on computed peak flows, such as the 100-year flows, that are used for designing bridges and other structures?
Flood map of Kansas link to real-time data for stream gaging stations and links to flood press releases, historic floods of Kansas, flood frequency data, photos, information on hydrology of floods, and flood hazard maps.
The so-called "100-year" flood is really more like the 4 ½ year flood. This can help emergency managers enhance public awareness of how often flooding truly occurs in a region. It also could help convince those people in harm's way that preparedness is m
Brief description of project for the Federal Emergency Management Agency to prepare and modify Flood Insurance Rate Maps based on flood frequency analysis, ground surveys, and flood profiles in Virginia.
We mapped substantial migration of the river channel between the City of Winslow and the Navajo Nation community of Leupp; in a human lifetime the river has moved more than a mile across its valley floor.
Storms bring rains strong enough to cause rock-falls and landslides that are hazardous to people. Includes examples in the eastern US with information about the weather events that precipitated the debris flows.
Photographic survey of the impacts of Hurricane Katrina on the barrier islands, barrier shoreline, and the Mississippi River Delta along the Louisiana coastline. Primary focus is on the ecosystems such as fish, rookeries, and seagrass beds.
The Maine Cooperative Snow Survey collects, interprets, and distributes information on the depth and water content of Maine's snowpack in the late winter and early spring, when the danger of flooding in Maine's rivers and streams is greatest.
The National Assessment of Coastal Change Hazards is a multi-year undertaking to identify and quantify the vulnerability of U.S. shorelines to coastal change hazards such as the effects of severe storms, sea-level rise, and shoreline erosion and retreat.
Research and monitoring to provide the Nation with a clear understanding of natural hazards and their potential threats to society, and assists with developing smart, cost-effective strategies for achieving preparedness and resilience.
Shows where current natural hazard events are occurring within the US or worldwide, with information about the geographic extent of the hazard, the US agency engaged to work on it, and how long the hazard is expected be active.

Topics in Coastal and Marine Sciences provides background science materials, definitions, and links to give a common context for users from a variety of backgrounds. Coastal erosion was chosen as the first topic.
Overview of research in the Hawaiian Islands and Guam to gain insight into the structure of coral reefs, to provide the basis for future monitoring, and to understand the influences of natural processes and human activities on coral reef health.
