Is there a way to use results from a PCSWMM H&H model and delineate the flood extent in GIS? All water surface data is contained in a point layer. Current process is to draw a cross section line at each point to generate a TIN surface for the water surface elevation. After watching the videos of the HAND method for a single depth I am wondering if it’s possible to use variable depths based on the point output from PCSWMM?
I have a DEM for the watershed, poly line layer for the streams and a point layer for the nodes along the stream.
I am using ArcGIS Pro 3.1 but have access to arcmap 10.6-10.8.
