Estimation of Natural Groundwater Recharge

Abstract

Water in arid and semiarid regions of the world is commonly recognized as the most important of the natural resources. Groundwater is commonly the only source of water in an arid or semiarid environment and, if not, it commonly is an essential and dependable supplemental source. Arid and semiarid environments are becoming recognized as potentially favorable for the disposal of waste products of man's activities. The basis for intelligent management of waste and water resources is quantitative information on the physical properties and flow components of the hydrologic system.
