Rechrage SWAT

[Elhem Gandouzi]

Hello, 

I am modeling in a region characterized by the presence of clay geological formation, so in reality the recharge (percolation) in some region is zero. Do you have any ideas on how I can block the percolation completely? I tried with the addition of a last layer of thick clay in the files *soil, but there is still a small amount of water that percolates. 

Any suggestion please? 

thank you
