Inundation Mapping Science in Texas

Science Center Objects

Flood-inundation maps created by the USGS Texas Water Science Center (TXWSC) allow users to view the possible extent and depth of flooding during a specific type of storm event. Flood inundation maps may be created using hydraulic models or by using data collected after a storm event (high-water marks). Visit the links below for more information on our data and science.

INUNDATION MAPPING SCIENCE CAPABILITIES

TXWSC has expertise in a wide variety of inundation mapping science applications, including, but not limited to: 

  • Modeling rivers and streams using hydraulic packages such as HEC-RAS
  • Developing decision support systems
  • Marking and surveying high-water marks
  • Determining peak discharge from indirect measurements
  • Analyzing flood-peak magnitudes and their statistical probabilities at selected locations
  • Analyzing high-water mark locations and elevations using geographic information system (GIS) to produce flood-inundation maps
  • Developing web-mapping applications for inundation extent and depth
