Flood Inundation Map Libraries for Indiana Communities

The U.S. Geological Survey (USGS) Indiana Water Science Center, in cooperation with the Indiana Office of Community and Rural Affairs, Indiana Department of Transportation, City of Fort Wayne, City of Indianapolis, Indiana Department of Homeland Security, Indianapolis Museum of Art, and the Indiana Department of Natural Resources – Division of Water, is developing flood inundation map libraries at streamgages and collocated National Weather Service flood forecast points across Indiana. This work is being undertaken as a collaborative project of the Indiana Silver Jackets Hazard Mitigation Task Force. The effort also is part of a larger Flood Inundation Mapping Program being undertaken by the USGS and partners: http://water.usgs.gov/osw/flood_inundation/.

Flood-inundation map libraries consist of maps that have been created in advance of a flood that are ready to be served through the Internet- each library consists of a set of flood extent and depth maps developed for predetermined stream stage intervals (for example, a map for each one foot of stage). A user can view real-time or forecast stage data from a USGS streamgage or National Weather Service (NWS) flood forecast point and quickly access the map corresponding to the stage data.

As map libraries are completed, they will become available through an interactive Web viewer: http://wi.water.usgs.gov/wim/flood_inundation_mapper/index.html.

Maps also will be available for select flood forecast points through the NWS Advance Hydrologic Prediction Service Web pages: http://water.weather.gov/ahps/inundation.php.
