How to Calculate Evaporation of Groundwater in FEFLOW

Hi! I'm wondering about how to calculate evaporation in FEFLOW.

In my model. the limit depth of phreatic evaporation is 1.5m, and the evaporation rate is 0.0008mm/d. Then I want to get the result of evaporation in my model area. It is an important item in water balance.

So can you tell me how to achieve it in FEFLOW and list the formula in detail which I think should be used in "In/out flow on top/bottom"?

Looking forward to your reply! Thanks!

Hi, the best way to start with this is to watch the ""how to" animation available at the Feflow website.
Let us know if you have further questions after seeing it.
