ScarceThe scarce water challenge for the mankind is an important problem. for mankind. Decision makers attempt to have the best operation from the available resources. Water storages behind dams are important resources which can be used for critical or drought periods. Todays, the researchers used mathematical tools for resources operation such as the water resource in the dams. Water resource management is a science which allows to us to have the optimal operation from resources. In fact, time and amount of water release is important for decision makers in the water supply filed (Zhang et al., 2014). Researchers have suggested the different mathematical models or methods for water ...
