Does anybody know of a solid way to map runoff/inundation areas from a single point source?&nbsp; For example, I would like to model the predicted floodplain/inundation area if a 1000 gallon oil tank suddenly ruptured in an urban environment.&nbsp; The model should take into account terrain (DEMs), land cover (I have very accurate data that I can convert to Manning's roughness coefficients), culverts (and other water-related infrastructure features), obstructions (buildings, structures, etc.), etc.</P><P></P><P>I've experimented with using the USACE HEC-RAS program, but haven't had luck finding solutions for single point-source mapping. Does anybody know of similar situations/tutorials that I could read up on or geoprocessing tools that I could use for this situation? Any help is greatly appreciated, thanks very much!</P></BODY></HTML> Wed, 30 Sep 2020 19:33:30 GMT GrantSmith 2020-09-30T19:33:30Z Point source flood mapping https://community.esri.com/t5/arcgis-pro-questions/point-source-flood-mapping/m-p/94236#M3856 <HTML><HEAD></HEAD><BODY><P>Hello everyone!
