Webb16 mars 2024 · The runoff from impervious and pervious surfaces was 14.38 mm and 10.80 mm, respectively, contributing to a total runoff of 25.18 mm. This total runoff corresponds to a volume of 0.17 x 10^6 liters and a peak runoff rate of 0.13 CMS. The runoff coefficient for the subcatchment is 0.773. Your runoff Coefficient is high due to … WebbRational Method: In this method, the peak rate of runoff is given by the equation-. Runoff coefficient C is defined as the ratio of the peak runoff rate to the rainfall intensity. … 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. black history pics and quotes
