Calculate discharge required for irrigation (Irrigation demand) for given condition. Also design well diameter to pump calculated discharge for the soil of hydraulic conductivity 8.42 m/d of unconfined aquifer. Observation well, which is about 200 ft from well shows constant water table of aquifer is 100 ft. You are allowed to draw-down maximum 60 ft of water table when pumping discharge
