What is it about?
Balance use of retention space between conservation and flood control purposes is usually necessary for the operation of a multipurpose reservoir. Guidelines on the efficient retention assignment are obtainable from dynamic rule curves developed using a based actual flood of considered return period. However, the shape of the flood varies widely and this necessitates development of a procedure to apply the rule curves for the reservoir operation versus various floods.

Why is it important?
We propose an operational procedure of a multipurpose reservoir for different floods using a set of dynamic rule curves of based actual floods. The proposed procedure uses related-size flood characteristics such as net retention of the dynamic rule curves and peak discharge of associated outflows to avoid taking a large variation in actual flood shapes into consideration. The proposal applies these flood properties for the operation of the reservoir in stepwise manner from those of the smallest flood to the largest one so that prediction on size of an arriving flood is not necessary. The procedure is feasible for the operation of a reservoir for different historical floods and applicable for assessing the impact of climate change on its operational performance.
