WebUnit Hydrograph The hydrograph of direct runoff that results from 1-inch (or 1 unit) of excess precipitation spread uniformly in space and time over a watershed for a given duration. The key points : 9 1-inch of EXCESS precipitation 9 Spread uniformly over space - evenly over the watershed 9 Uniformly in time - the excess rate is constant over the time … WebClark Unit Hydrograph Method The Clark method is a well established unit hydrograph approach to rainfall runoff simulation in which the basin shape, watershed storage, and timing can be accounted for. However, rainfall and loss parameters are lumped by determining average values over the domain. The Clark model is one of a handful of …
