Almost all multipurpose reservoirs in Romania were put into operation 30–50 years ago or even earlier. Meanwhile, a large volume of hydrologic data has been collected, and the initial design flood should be reconsidered. Consequently, operating rules flow control structures (bottom gates weir gates) re-examined, mainly for medium low-frequency floods. The is not unique, being characterized by different shapes time to peak, which consequences mitigation rules. Identifying critical an important preliminary step, although it usually neglected management. Simulating Stânca–Costești reservoir on Prut River, was found that corresponding maximum value compactness coefficient most difficult mitigate considering specific conditions dam reservoir: prescribed conservation level reservoir, rare floods far exceeds volume. These can jeopardize both safety downstream protection. main steps proposed approach are as follows: (1) developing hydraulic model; (2) statistical processing registered defining AEPs (Annual Exceedance Probabilities); (3) deriving optimal based simulation-optimization (4) implementing real-time adaptive mechanical outlets; (5) critically assessing after event. Based hydrological forecast, if necessary, new outlets while keeping ones already activated. forecast properly operated, guaranteed event 0.1% CC (Climate Change) flood. However, greater than 1% magnitude, carrying capacity riverbed exceeded. gaps addressed this paper following: establishment floods, outlet devices aimed at optimizing results, using short-term forecasts.
