NHDPlus Inundation Modeler (NHD-IM) v4.0 Beta was developed as an extension of ArcGIS 10.3 or later versions and allows users to perform hydraulic steady flow calculations and rapid inundation boundary delineation, while fully taking advantages of ESRI’s spatial analysis and data manipulation capabilities. This ArcGIS toolbox provides three major functions: 1) Automated cross section construction; 2) NHD flowline bathymetry generation; and 3) Flood inundation modeling and mapping.
