Review on Scope of Groundwater Modeling

We all know that the earth contains 70% of water and of 30% Land surface. But from that 70% of water 97% is saline water and we cannot use that water in our day to day life. Now a day the only source of pure water comes from the sub-surface. So that we need to improve the technique to bring out as maximum pure water as possible from the sub-surface. For that groundwater modeling is required. For this purpose many software are available which gives the idea about the lithology and movement of groundwater flow direction. In this paper we are giving the literature review on the groundwater modeling which gives brief idea about groundwater study. Groundwater is the most important source of drinking water in India. Especially it plays a vital role in the development and public health of the population in arid and semi-arid zones. Unfortunately due to injudicious and unplanned urbanization and Industrialization for the past few decades in few parts of the country, the resource is either being depleted or degraded in quality.
