The examined region is surrounded by mountains formed by a bowl shaped depression in the Paleozoic strata and granite. The paleozoic strata basin rock is an impermeable bed upon which there is a permeable diluvium and then alluvium. It is estimated a lot of groundwater is saved. However, if an excessive pumping is continued, it can cause the exhaustions of the groundwater and the subsidence, and especially multiple wells which take a large amount of water in a small area are considered to have a great impact. We established a 3D model for groundwater and make suggestions for the adequate management of the groundwater by a pumping simulation analysis. This simulation was the subject of which was a pumping well for water service - water levels for one pump were large. As a result, it can be seen from this that the fluctuation of water level group wells cause accuracy by using our model made in the present study., 12th ISRM International Congress on Rock Mechanics "Harmonizing Rock Mechanics and the Environment" 18-21 October 2011, Beijing, China}, title = {Pumping simulations using 3D analysis on multi-pumping wells}, year = {2011} }
