HEC-GeoRAS

HEC-GeoRAS is a powerful software tool that combines the capabilities of HEC-RAS, a widely used hydraulic modeling tool, with ArcGIS, a geographic information system (GIS) platform. This integration allows users to seamlessly leverage spatial data and GIS functionality within the HEC-RAS environment, enhancing their ability to perform comprehensive hydrologic and hydraulic analyses.

What is HEC-GeoRAS Used For?

HEC-GeoRAS is primarily utilized for:

• Hydrologic and hydraulic modeling of rivers, streams, and other water bodies: HEC-GeoRAS enables users to create and analyze hydraulic models of rivers, streams, and other water bodies, considering factors such as flow rates, water depths, and channel geometry. This modeling capability is essential for flood risk assessment, dam and levee design, and other water resources management applications.
• Spatial data management and analysis: HEC-GeoRAS allows users to import, manage, and analyze spatial data related to water resources systems. This includes terrain data, land cover maps, and other geospatial information that can be used to inform hydrologic and hydraulic modeling. By leveraging GIS capabilities, HEC-GeoRAS provides a comprehensive platform for spatial data analysis and visualization.
• Floodplain mapping and risk assessment: HEC-GeoRAS is widely used for floodplain mapping and flood risk assessment. Users can create flood inundation maps that depict the extent and depth of flooding under different scenarios. This information is crucial for emergency planning, land use management, and flood insurance purposes.
