RTi has developed and implemented flood inundation mapping tools using streamflow forecasts from RTi's RiverTrak and the National Weather Service River Forecast System (NWSRFS), as well as using surface water profiles from HEC-RAS. Flood inundation maps can be prepared at regular intervals using real-time hydrologic data collection systems to provide users with observed and forecasted flood inundation maps. The maps can be displayed using a variety of standard GIS tools.

Flood inundation maps are useful for emergency management teams, city and county water departments, forecasting agencies, fire and sheriff departments, hydropower enterprises, and water managers in both the public and private sectors.

Hurricane Mitch RiverTrak Flood Inundation Mapping Demonstration

The RiverTrak flood inundation mapping demonstration displays data from the Choluteca, Honduras area, for the Hurricane Mitch event of 1998. This demonstration illustrates the use of ArcIMS with RiverTrak and has been tested on Windows versions 98 Second Edition and newer using Internet Explorer version 5.5 or more recent. It is designed for a screen resolution of at least 1024x768. Use the demonstration's help (?) button for more information about running the demonstration.
