Computation of ground water contamination by using modflow

11 ABSTRACT Groundwater is the source for drinking water for many people around the world. Virtually all the homes that supply their own water have wells and use groundwater. So the quality of groundwater is of paramount importance. In such cases the groundwater has been contaminated by the acts of humans. In addition to providing for the sustenance of human life, groundwater has important ecological functions. Many freshwater habitats are supplied by the discharge of springs. If the groundwater supplying these springs is contaminated, the ecological function of the freshwater habitat can be impaired. The wastes of industrial plants which are located near the groundwater sources are the common reason of groundwater contamination. In this thesis groundwater contamination model is applied to the Harmandalı Sanitary Landfill Area and to a heterogeneous aquifer by using the PMWIN MODFLOW. The numerical results obtained from the computer program are discussed.
