Due to the increasing demand of fresh water in Bandung, the capital city of the west Java Province, the Republic of Indonesia, since 1980's, the municipal government and private firms have started to use deep groundwater through deep wells.
This project report investigates the impact of this development on the pattern of deep groundwater flows and the environment by means of a two dimensional computer model. A computer program called AQUIFEM-1 is used.
The conceptual model, consisting of a triangular finite element grid with 164 nodes and 289 elements, which represents the study area of about 325 km2. The results are shown either on printing outputs or on graphs that show the changes of the groundwater flow pattern. It is concluded that, the total existing well discharge of about 666 m3/day does change the groundwater flow pattern significantly depleting the volume of the water in the aquifer. This may cause the shallow wells located in the area to dry up, heavy constructions on shallow footings may experience additional settlement, and subsidence over part of the area might occur in time.
