WebMost of the practical storms vary in duration, amount, and distribution of rainfall. A unit hydrograph is a hydrograph of a rainfall of a specified duration and areal pattern, resulting in a run-off of 1 cm. In other words, the total volume of water contained in this run-off hydrograph will be equal to 1 cm depth of water on the catchment.
