Abstract: Flood retention basins often require a large volume to be effective. The volume can be derived simply from frequency considerations of the volume of a relevant flood wave and the water level to which the downstream region should be protected. If the available storage in a reservoir is less than required, a certain protection can still be reached, but then the time of opening the reservoir is crucial: both opening too late or too early results in less protection than possible. An active operating policy is needed, which requires probabilistic flood forecasts.
