Scheduling and Built-in Management of the Resources in Waterof the Basin Pouring of East-Kebir River (North-East of Algeria)

In Algeria water is a resource as much more important than it is rare. It is a country semi arid or even arid (200-400 mm) and resources are distributed unequally (localized in tea inshore strip) and extensively used (notably the reserves in underground waters). indeed Algeria is located among countries poorest in matters of hydrological potentialities is below 1000 m3/year/capita. currently tea availability in theoretical water per capita and per year is estimated to 500 m3 and would be even more reduced brought back to resources in mobilized water. In Algeria on l19.5 billions of water meters cubes recognized mobilizable 12.5 milliard of m3/an stream indeed toward the sea and chottses and the present mobilization is hardly 2 billions of m3. Besides the competition that deliver to himself agriculture the industry and cities to have access to these availabilities in water strike of now and already efforts of development of or the vital importance that dresses the big questions relating to the mobilization and the management of water. So one meets in the paradoxical situations even in the rich in water recognized regions whose users see their needs far from being satisfied: - such is the case of the basin pouring of east kebir river. The basin pouring of east- kebir river is part of the inshore pouring basins of the north extreme is Algerian, a surface of 1200 km2s presents the paradox to be a rich in water recognized region with potentialities important hydrological (climate Mediterranean sub - humid with a yearly rainfall superior to 800 mm) , materialized on the one hand by the almost permanent flooding during seasons autumnal and wintry and sometimes vernal and has flagrant water lack at the level of the defers users marked by restrictions operated by the technical services (rationing through cuts of water of ORSEC plan and restrictions in irrigated perimeters) Only one hydraulic work of big enough span exists at level of this : It is basin dam of Mexa. So therefore the problem puts itself in terms of mobilization that in terms of availabilities. The goal pursued in this note is the understanding of problems may one hand for the satisfaction of demands in water and to their possible solutions and in the other hand, that cannot be made that in the setting of has scheduling by the slant of the hydraulic planning while taking account of the defers: Surfaces components of uses, organs of accumulation and affectation of resources. The recommended planning took account of the existing infrastructures however under realization one hand and was spaced out for the setting up of the defers works of storage and perimeters of irrigation in the other hand. The gotten results permitted to raise the problematic of the water use in the basin pouring of east-kebir river is in view of its better restraint of this wealth that rarefied from day to day considering has more and more increasing demand and that all management efficient and rational waters must make h
