Request for helping for Water Balance Check

[Liton Chandra Mazumder]

Hi Everyone,

I run the SWAT+ model. After simulation of the model, I have checked water balance. However, water balance is not close to zero in my case.

In my case, rainfall is 1150 mm, surface runoff 628 mm, ET 301 mm, lateral flow 68 mm, percolation 297 mm, seep 23 mm and groundwater flow is 425 mm.

I also attached my water balance and aquifer file (csv).

could you kindly tell me, where is the problem and how to calculate water balance?

any other suggestions would also be highly appreciated.

I look forward to hearing from you.

Thank you and best regards,

Liton Chandra Mazumder
