Field notes
The editor says it changes only the row being edited and preserves other file details, including comments and unknown sections, through a round trip. For flood analysis, users can supply an ESRI ASCII grid or GeoTIFF, choose between local-inertial and full-dynamic solvers, and view depth, velocity, and hazard grids alongside SWMM results. The site notes that this 2D work has not yet been checked against a measured real-world event.
