<br />
<br />
groundwater areas developed by BP.P2AT one of the Central Java. Research area is included deposit unit of volcanic alluvium, known as fan alluvium Balapulang. The stream pattern of the rivers is sub-parallel and sub-denditric with the main rivers is Gangsa river, Pagerwungi river, Pagerayu river, and Rupak river, <br />
<br />
<br />
<br />
<br />
The aim of this research is to found the groundwater balance in the mndel area, through simulation by the visual Modflow 27,2 program. The conceptual model was made based on the electrical resistivity, with 90 km2. Based on electrical resistivity, the model area consist of four layer, in series from upper layer one; volcanic brecia, mixed-sandy clay, sandy tuff, and clay. <br />
<br />
<br />
<br />
<br />
The simulation was conducted in twice ; on condition before and after well the pumping. The number of deep well pump are2Swells total rate of 45,599,3312rn3/day. <br />
<br />
<br />
<br />
<br />
From the result of simulations, the amount of groundwater inflow to model area before pumping is 871'425.01 m3/day and the outflow is 841,780.19 m3/day, so that there is 29.644.82 m3/day remain. While after pumping, inflow is 898.030,89m3/day outflow is 872,110,69 m3/day so that there is 25,920.2 m3/day remain. |
