Hello everyone,

I am working on a SWAT+ model and facing an issue with the water balance.

I am getting very high evapotranspiration  and very low runoff, even though annual precipitation is around. Groundwater and lateral flow are also very low. 
Has anyone experienced a similar issue or can suggest what to check first?
