Abstract: This paper presents the results of studies performed to determine the effect of water extraction time from the river on the performance of off-stream reservoir. In total, a fixed volume of water is transferred to the reservoir by ten scenarios combining different months and optimised release is determined using dynamic programming. Then, indicators evaluating the performance of the reservoir are considered. The results showed that extraction of water in June and lack of water extraction in April led to maximum improvement of volume reliability while water extraction in May and lack of water extraction in April causes maximum improvement in the number of months facing water shortage. Also, water extraction in March and lack of water extraction in May led to maximum improvement of maximum seasonal shortage indicator while lack of water extraction in March improved duration of water shortage indicator.
Keywords: off-stream reservoirs; water extraction time; rivers; optimisation; dynamic programming; water shortage.
