WebIntroduction to Unit Hydrographs. A unit hydrograph shows the temporal change in flow, or discharge, per unit of runoff. In other words, how the flow of a stream will be affected over time by the addition of one unit of runoff. The unit hydrograph is a useful tool in the process of predicting the impact of precipitation on streamflow. Webv. Obtain storm runoff for each rise. vi. Select durations of precipitation excess (T e) by inspection of hyetograph and hydrograph. vii. Plot mass curves of rainfall and obtain cumulative rainfall values (Pw 1, Pw 2, Pw 3 etc.). viii. Plot mass curves of direct storm runoff and obtain cumulative runoff values (Qs 1, Qs 2, Qs 3 etc.). ix.
