The U.S. Geological Survey (USGS) is one of three federal partnering agencies under the Integrated Water Research Science and Services (IWRSS) consortium involved in moving the science of Flood Inundation Mapping (FIM) forward for the primary purpose of public safety, along with significant benefits of understanding changing natural processes that produce hazards, development of hazard mitigation strategies and technologies, effectively reduce vulnerability and repetition of loss to infrastructure, and the promotion of risk-wise behavior.
The Flood Inundation Mapper is a mapping tool for flood response and mitigation. The mapper shows digital geospatial flood-inundation maps of flood water extent and depth on the land surface. This real-time dynamic flood inundation mapping application reports USGS historic and current station conditions, National Weather Service (NWS) prediction information and Federal Emergency Management Agency (FEMA) HAZUS loss estimations within the mapping application. HAZUS uses Geographical Information Systems (GIS) technology to estimate physical, economic, and social impacts of disasters.
