A spillway of a dam, for example, is hit not by the natural hydrograph with its peak discharge of the catchment but by a design discharge significantly attenuated by the retention effect of the reservoir: flood volume counts, and therefore, the design work is usually based on the hydrograph rather than the peak discharge rate. © 2014 by Taylor & Francis Group, LLC.en10.1201/b15625info:eu-repo/semantics/closedAccessBook Chapter311328N/A
