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
