Dimensionless unit hydrograph (DUH) - a hydrograph developed to represent several unit hydrographs; plotted using the ratio of the basic unit’s time to peak and peak rate; also called an index hydrograph.

The unit hydrograph is defined as the hydrograph of direct runoff that results from 1 inch of excess rainfall generated uniformly over the watershed at a constant rate during a specified time.
