P.E., Ph.D. inasseri@usc.edu Office: (310) 963-6124 Water is essential for human consumption and sanitation, for the production of many industrial goods, and for the production of food and fiber. Population and economic growth demand for more water. Water either as surface water or groundwater is unequally distributed on the earth, and its availability at any place varies greatly with time. The demand for water also varies with time at any place. This lack of harmony between supply and demand calls for a careful management of water resources. Management of water resources is influenced by economic, environmental, legal, political, and social considerations as well as engineering facts. Traditionally, management of water resources has focused on surface water or groundwater as if they were separate entities. Effective management of water resources must be built on a foundation that surface water and ground water are simply two manifestations of a single integrated resource. Nearly all surface-water sources (streams, lakes, reservoirs, and estuaries) interact with groundwater. Withdrawal of water from streams can deplete groundwater or conversely, pumping of groundwater can deplete water in streams and lakes. Pollution of surface water can cause degradation of groundwater quality and conversely pollution of groundwater can degrade surface water. Meeting the increasing demand for water requires significant improvements and innovations in how to optimize our existing water supplies to balance water demands. One proven way is to store excess water during wet years beneath the ground for use during dry years. This coordinated management of surface water and groundwater is called conjunctive use. The conjunctive use concept is intended to increase total supplies and enhance water supply reliability.
