Error message

[ni00su]

Hi,

I am currently using HEC-HMS 3.3 for rainfall-runoff simulations and getting a following error message. I tried to press control key during simulation, as suggested by someone earlier, but it didn't help me. I would appreciate if anyone can suggest me why.


Error 41200: One or more outflows from element ‘Aubrey Falls’ could not be found. Outflows were needed as inflows to element ‘Aubrey falls lake’

Not enough info.

What outflows? Are you generating a hydrograph? What is the flow of your model (what attaches to what, etc)

Some more details:

I am trying to generate a hydrograph from a basin. Aubreyfalls is a subbasin that flows into Aubrey Falls Lake. The model was supposed to generate a hydrograph for given precipitation based on SCS method. I hope this allows the expert to identify my problem. With thanks.

I got it solved. Firstly, the error message was particularly found to arise while simulating snowmelt. Secondly, the model had difficulties in interpolating daily temp (input) into hourly temp. for hourly simulation. When the input (daily temp. in this case) was manually changed to hourly, the errors are gone.
