RAS2FIM is a software repository designed to generate Flood Inundation Mapping (FIM) geospatial grids from one-dimensional Hydrologic Engineering Center - River Analysis System (HEC-RAS) flood simulation models.
RAS2FIM is maintained by a small team of at the NOAA National Water Center, but all are welcome to collaborate.
The repository is currently undergoing a significant documentation phase. Please refer to the CHANGELOG for the latest updates. Check out the RAS2FIM Quick Facts or the Known Issues and Opportunities for Improvement pages. Check out the README for information on getting started and to see scientific credits and references.
Development initially started in 2019 with the Center for Water and the Environment of the University of Texas by Andy Carter under the guidance of Dr. David Maidment. In 2021, the code base was refined through the NOAA National Water Center by the Flood Inundation Mapping team. The first public release was 7 Nov 2021.
