Fig. 3From: Surface storm flow prediction on hillslopes based on topography and hydrologic connectivityThe width function-based geomorphologic instantaneous unit hydrograph (WFIUH) of a watershed equals the sum of the WFIUHs of representative elementary hillslopes A through G. The total runoff is a function of the travel time distribution within the watersheds, and varies depending on flow velocity and channel network configurationBack to article page
