Groundwater pumping simulation using hydrology apparatus

Groundwater is water located beneath the ground surface and underground water movement in soil and rocks. There are many method of obtaining hydraulic information from aquifers, but perhaps the most common and best is the pumping test or aquifer test. Without an estimate of the hydraulic properties...
