I am very new to HMS. I set up a model and got errors on all the basins stating
WARNING 42374: Output unit hydrograph volume does not match unit volume for subbasin
and the differences were in the thousands of percents (1,656.73%, 1,934.73%, 8,980.46%).
Any idea of what I might have done wrong?
For unit hydrograph, I used USBR Flood Hydrology Manual ( ) table 4-13.
Thanks!!!
