Hydrogeology is the science which mainly deals with the groundwater. In the broadest sense, hydrology addresses:
  • occurrence,
  • distribution,
  • movement,
  • and chemistry of all waters of the earth.

Evaporation and Transpiration

The process through which water is transferred from the surface of the Earth (land surface, free water surfaces, soil water, etc.) to the atmosphere is called evaporation.During evaporation process the latent heat of evaporation is taken from the surface of evaporation.Therefore evaporation is considered as a cooling process. Evaporation from land surface, free water surfaces, soil water, etc. are of great importance in hydrological and meterological studies,
