Elaboration d'un modele de gestion en cas de sécheresse dans l'éxploitation du barrage de Koudiet Acerdoune.

Abstract

Water, being a vital natural resource and making the object many uses, imply a schedulingof his management in different aspects and to different horizons. This management is willbecome more and more complex and complicated in the future. It is due, to the demographic growth and to the improvement of the standard of living. This work is centered on the management of the dam of Koudiet Acerdoune with the helpof a stochastic dynamic programming, set in motion a code of calculation « MODMAN »,elaborate with Scilab. Two objectives have been chosen: the first consists in satisfying the demand of the differentsectors while giving the priorities respectively to the food in drinking water, industrial and theirrigation and the second to guarantee a volume of security for the dry year that follows theyear of survey. The model is tested on different periods: dry, average, humid and debit reconstituted thanksto PCA.
