Method Of Optimal Operation Of Small Dam In Irrigation

Abstract

In several Arab countries; agriculture is considered as the largest user of sweet water. This noble resource is distributed erratically by time and space. For the month of irrigation, this resource became scanty. That’s why; it is require to storage it; protect it and use it reasonably based on a deep knowledge of hydro meteorological policy and irrigation. This contribution is to propose the hydrological method of exploitation if the resource of water regulate by a small water dam. This is ascertained by the equation of the hydratical balance. Because it is possible to improve the yield of the water dam by the apliment of operating rules during irrigation season based on probabilistic projections of the fundamental components of the water balance.
