WebbLet’s consider two unit hydrographs for the same basin. For the green line the unit is 1.00 inch. For the blue line the unit is 1.0 cm. Since 1 cm is only 39% of 1 inch, we can see that it is a curve with lower magnitudes, but the same timing. Now let’s consider a storm that produces 0.75 inches, or 1.9 cm, of excess precipitation.

How to Convert IDF Storm Data to a Time-Depth Storm Event

WebbTo match the runoff depth given by the SCS runoff equation, the time span must include all times at which runoff will occur. To "see" the entire runoff volume (and the equivalent runoff depth) the time span must end sometime after the end of the storm. For a 24-hour storm, a span of 0-30 hours will generally include all the runoff.
