<b>Abstract:<p align=\"justify\"> <br /> \"Taman Buah Mekarsari\" is an agrotourism area, which is located in Kec. Cileungsi, Kabupaten Bogor, aimed to create a horticultural garden, production garden, horticultura pilot project and agrotourism. Until 1992, 9 wells has been drilled by P2AT and another 9 wells were drilled by PT. Sarinande Agung. Those wells were utilized for irrigation, potable water of PDAM Cileungsi, potable water in the Taman Buah Mekarsari complex, water fall and fishing pool. With an area of 223 hectares, well discharge between 5 - 15 1/second, and pumping operation about 8 - 11 hours per day, and aquifer thickness of 35 meters, it was worried that groundwater over exploitation will be occurred. <br /> The precipitation in this research area is 2500 - 3000 mm per year, with rainy season in April-September. Stratigraphy of this study consist of alluvial fan, young volcanic deposits, old volcanic deposits and sediments of Subang formation. The aquifer transmissivity in the study area (T) is 163.29 - 317,09 m2/day and Storage Coefficient (S) is 4,92.104 - 2,06.103. <br /> Simulation of the system groundwater has been carried out using Modflow software version 2.60 . <br /> The results of the ground water simulation in the study area show that the lowering of the piezometric level is about 1,14 - 5,32 meter per year. <br /> The groundwater flow line in the study area, which was initially from the south to the north is predicted to change to the northwest and northeast and from the north to the south where TW-91, TW-92, and TW-93 wells are located.<p align=\"justify\">
