AbstractDue to increase in population and occurrence of extreme droughts in recent years, correct management and planning of water resources are essential and considered vital needs in the Middle East countries. Optimal water release from reservoirs is part of water resource management. For optimization of water release from reservoirs, different methods can be applied. In this research, dynamic programming (DP) method (a discrete method for optimization) and stochastic discrete programming (SDP) method (a stochastic discrete method for optimization) are considered for optimal operation of Dez dam reservoir. The Dez dam locates in the southwest of Iran. Useful storage of the reservoir of the Dez dam is 2993.27 Mcm. This dam was constructed in 1963. This research shows that reliability and resiliency of SDP method are higher than those of DP method, whereas vulnerability of SDP method is less than that of DP method. Also, SDP method can show months in which deficits occur correctly. The number of deficits in SDP method is less than that in DP method. In addition, in this research, variations of the number of deficits are evaluated in relation to variations of inflow to the reservoir. Sensitivity of DP method to variations of inflow to the reservoir is higher than that of SDP method.
