WebLesson 22 Stream Flow Hydrograph. 22.1 Definition of Hydrograph. The hydrograph which results due to an isolated storm is typically singlepeaked skew distribution of discharge and is known variously as storm hydrograph, flood hydrograph or simply hydrograph. The hydrograph is the response of a given catchment to a rainfall input.

WebA runoff hydrograph represents the cumulative runoff resulted from surface and sub-surface (base flow) runoff. The surface runoff or direct runoff hydrograph is obtained from the total storm hydrograph by separating the base flow. The separation of base flow is an arbitrary manner, unless a large flow from the antecedent storm is available.
