Pumping Simulation using 3D Ground Water Flow Model in Kyoto

The area of the analytical model is located in the southern part of Kyoto prefecture, it has a typical ground water basin shape and three rivers flow through it. The rivers flow into the area between two mountains, then flow out to Osaka. Due to the fact that the underground water in the basin flows out from this point only, it is estimated that abundant underground water is saved in the Kyoto basin. This research is focused on Joyo city which has long used plenty of underground water for the public, agricultural and industrial water supplies. In recent years, excessive pumping has caused subsidence and the depletion of water resources. This research purposes to establish a three dimensional groundwater flow model and make suggestions for the adequate management of the underground water by a pumping simulation analysis
