Though groundwater and rainfall correlate with each other, the recharge from rainfall into the groundwater system depends on other terrain elements. In the present study, the terrain parameters such as lineament density, drainage density, slope percentage, thickness of soil, weathered and jointed zone, average annual rainfall and mean groundwater level were subjected to multivariate analysis. The interrelations of the variables were brought out.Functional models have been developed to understand the functions of groundwater level.
