Direct and total flow

2 posts in this topic

Hello

When running HEC-HMS, the difference is so big between the direct flow and the total flow; for example direct flow (1000 M3/s) and total flow (30 M3/s), see attached file, is there any explanation for that big difference?

Best regards

Something strange is going on with your model.  Normally, Total flow = Direct flow + Baseflow and the numbers do not add up for your model.  Also the (Excess * Basin Area * unit conversion factors) should = Direct flow.  Are you getting any warnings when your run your HMS model?  If so, what are they?  What kind of model are you running?  Is it a ModClark simulation?  If you contact technical support they may be able to help you.
