utm virtual machineA unit hydrograph (UH) (Fig. 3.1.23) is the hydrograph of direct run-off (i.e. excluding baseflow) produced by a rainfall event of unit depth (usually 1 cm) over a certain period of time. For example, a 1 hour unit hydrograph is the hydrograph produced by a rainfall event producing one unit (1 cm) of rainfall over 1 hour.

Therefore to convert the Unit Hydrograph ordinates to Flow it must be multiplied by a rainfall depth (p, cm). The Time-Area ordinates are multiplied by a rainfall rate (i, mmhr) to convert them to Flow. The constant 2.78 converts (mmhr ha) to (ls) in the rational and time-area methods a more accurate conversion is (1.00.36). quot;>.
