Multi-Objective Quantity–Quality Reservoir Operation in Sudden Pollution

Shokri, Ashkan; Haddad, Omid Bozorg; Mariño, Miguel - In: Water Resources Management 28 (2014) 2, pp. 567-586

Damage caused by entered pollution in reservoirs can affect a water resource system in two ways: (1) Damages that are caused due to consumption of polluted water and (2) damages that are caused due to insufficient water allocation. Those damages conflict with each other. Thus, the crisis should...
