I run the model with ICF curves, it works OK. Then I "saved as" and open the copy, have both Hydrology Method and TOC as SCS TR-55 and hydraulic Routing as Steady Flow with Haze-Williams equation. I created one Rain Gage (Rain data format type - Intensity with 5 min. increment interval) and assigned it to all subbasin. When I run the model it doesn't give me any error messages, but it is no flow in the system! Zero! Why?
