Abstract

Water is one of the scarcest inputs in most countries and is used in agricultural production. In Iran, where the average annual rainfall is 240 mm  with sporadic distribution and spatial and temporal variations, this input becomes more important. Sistan and Baluchistan is a dry province of the country that faces water shortage problem in many years. To solve water supply fluctuations and scarcity in Sistan region, Chahnimeh water reservoir was established to store water in wet seasons and, consequently, decrease damages in the dry seasons. The aim of this study was modeling of the Chahnimeh water reservoir management using goal programming to determine optimal water for domestic, agricultural, and environmental sector and its sensitivity analysis. Therefore, a matrix with 142 in 154 dimension of aims and systemic and goal constraints were constructed. Then, this model was solved using goal programming. Considering the historical data, results show that water requirement of domestic and environment sectors can be provided, but some agricultural water may not be supplied. Therefore, if in the first six months of the year water is stored in Chahnimeh reservoir, in the next six months, there would be no water shortage, Also, if irrigation efficiency increases, decision makers can increase the cultivated area.
