I understood my problem. I have changed the parameters of my loss method (again but much more), for instance the constant rate for the Initial and Constant rate model, and I now have "real" excess precipitation.
I just don't understand why this rate has to be so low (16 mm/h for a 24h-30mm...
Hi,
Thank you for your answer but I don't think this is the problem. I have used two precipitation methods and the problem remains.
First I used the "Gage Weights" method. Because it is a small watershed, I only used 1 gage point.
Then for each of my subbasins, I said "yes" to "Use Gage" for...
Hi,
I am a new user of HEC-HMS and I am having some problems with the choice of the loss methods.
I have tried several of them (Initial and Constant Rate, DEficit and Constant Rate, SCS Curve Number, Smith Parlange, Green Ampt). And for all of them, the only excess precipitation I get is from...
