Due to the diverse economic development in Taiwan, the total water demand boosted gravely, but for part of those areas, due to the lack of surface water, businessmen of some of those areas resorted to groundwater as the solution. Due to the cheaper cost of groundwater, and its stability of water quality and quantity, most of the businessmen dug groundwater considerably to make up for the lack of water demand of those target areas, however, this act not only caused improper use of water and soil resources, furthermore, due to the excessively use of groundwater in part of those areas, it caused land subsidence of plates with a large scale, and it affected the exploration and use of water and soil resources.
This research makes an estimate of the groundwater for the costal area in Kaohsiung(Yong-an Township and Jiading Township) by a method of experience、a method of the flow surveyed of the local well and a method of the electric power.
