i got monthly discharge data for a river in cumec unit. i wanted to use it in model as river head flow. the values were very high like 28000, 23000 etc. when after completion of data entry i run the model it show some messages like " there were warnings or errors during calculation". then when i clicked on the messages i found "Scenario Month Year Branch Message (Double-click to go to that variable in the Data View.)
0 In all, there were 5312 extremely large values, which might cause problems for the linear program (LP) solver. Only the details of the first 8 are listed (below).

Hi Adnan,
What is your discharge unit, CMS or MCM/Month? I think you have to check your inflow unit with the model unit? It seems there is an inconsistency in the model.

Hossein
