Meta-heuristic, or evolutionary, algorithms are known as the key tools infor assessing the water resource management problems. These methods can help to determine the optimal strategies, such as accurate release water volume or storage in the problems (Schardong and Simonovic, 2015). In thisSome researchers continue some researcherssuch assessments around reservoir operation, andwhere the use of evolutionary algorithms can be seen.

Akbari-Alashti et al. (2014) optimized reservoir operation, based on genetic programming and the results showed that the used genetic programming used could match with the downstream demand better than the genetic algorithm.
