Groundwater & Hydrology

Water is the most cast off natural material in the earth. Irrespective of variations in its supply with the pace of time and location its aggregate quantity remains constant. The transformation of the water takes place through a continuation process referred to as hydrological cycle deriving its momentum through the solar energy and gravity. Down pouring of rain consequent upon condensation of clouds are extracted by the roots of plants, flooded over the surface joining the streams and rivers and to some extent absorbed by the earth to form the reservoir of underwater. Vaporization of water from water reservoirs, and transpiration of plants makes the water back to atmosphere.

The invisible underwater, which is the result of the continuous process of hydrological cycle, constitutes the key source of the water. This is also considered as the primary reservoir of pure water in a nation. Presently, the assessments...
