The factors to be carefully studied before selecting a site for sinking a well are: (i) Topography: The valley regions are more favourable than the slopes and the top of hill rocks. (ii) Climate: Maximum temperature, the annual rainfall region, intensity of sunlight and humidity are of considerable value. Semi-arid zones are more favourable than arid zones. (iii) Vegetation: (a) [...]
This article provides a diagram of hydrological cycle. The rain water that falls on the ground surface is divided into three parts: They are: (i) One part directly returns to the air as water vapour by evaporation and transpiration from plants. (ii) Another part flows over the surface in rivers and ultimately reaches sea or ocean. (iii) The third part [...]
A geological formation that is water bearing or saturated with water and is capable of yielding sufficient quantity of water for economic exploitation is termed as aquifers. Aquifer serves as a transmission conduct from storage reservoirs. It transports water from recharge area to surface bodies of water and other collecting devices. There are many types of aquifers. They are: 1. [...]
