8l/s pumping well simulation

hi everyone!!

Please, I need your help!! I would like to show how can the water table changed if we have a pumping well with a 8l/s flow for the next 365 days. That is the situation: A pumping well and two piezometers surrounding it at X meters. Day 0, we begin the pumping at 8l/s, K_ss 2.08m/d. Hidraulic head in the south 7m and in the north 5m. I would like to know how could affect this pumping to the water table, measuring it in the piezometers and the depression cone in the pumping well for the next 365 days. 

Thank you very much People

I forget to write that it is a confinated aquifer in the second and third layers and i dont know how to put impermeable boundaries.
