Groundwater withdrawal has been increased to a greater extent due to increase of population industrialization and agricultural practices. Moreover, disposal of various industrial effluents in water bodies, solid wastes in landfills has results in generation of leachate which percolates and reaches the groundwater table and get transported along with the direction of groundwater flow. Therefore, the use of groundwater flow models is prevalent in the field of environmental hydrogeology to investigate a wide variety of hydro-geologic conditions and groundwater models have been applied to predict the fate and transport of contaminants for risk evaluation purposes.
