Flood peak flow
WebJun 28, 2012 · The attenuation of flow is the difference in peak discharge between these two hydrographs-in this case, about 2.3 cms. The area between these two curves represents a volume of water. The area to the left, where the upstream discharge is greater than that downstream discharge, represents water going into storage.
