Determining Peak Discharge for a 2.5-Hour Storm

How can we calculate the peak discharge for a 2.5-hour storm with 2.5 cm of runoff using a 2.5-hr unit hydrograph with a peak discharge of 100 m3/s?

Calculating Peak Discharge

To determine the peak discharge for a 2.5-hour storm with 2.5 cm of runoff using a 2.5-hr unit hydrograph with a peak discharge of 100 m3/s, we can follow these steps:

  1. Convert the rainfall depth from centimeters to meters:
    2.5 cm = 0.025 m
  2. Use the given unit hydrograph peak discharge of 100 m3/s and substitute it into the formula along with the rainfall depth of 0.025 m:
    Peak discharge = (0.025 m) x (100 m3/s)
    Peak discharge = 2.5 m3/s

Therefore, the peak discharge for a 2.5-hour storm with 2.5 cm of runoff would be 2.5 m3/s.
