Developing Near-Real-Time Flood Impact Mapping in Texas
In August 2016, NOAA's new National Water Center in Tuscaloosa AL became operational in publishing hourly streamflow forecasts for all 2.7 million reaches of the NHDPlus river network, see http://water.noaa.gov/map. These are now being adapted for use by the Texas Division of Emergency Management (TDEM), to help local public safety officials anticipate flood impacts anywhere in the state. Part of the process leverages an elevation raster called Height Above Nearest Drainage (HAND) which is developed from a standard DEM, and represents the vertical height above the nearest DEM drainage line from each grid cell. This presentation will be about the work-in-progress, current challenges, and next steps.
