Reduced Peak Discharge Calculator

Calculate the reduced peak discharge from a retention/detention pond storage volume using:
\[ Q_r = \frac{V}{\Delta t} \]

* Enter the storage volume \(V\) (ft³) and the discharge duration \(\Delta t\) (s).

Step 1: Enter Parameters

Storage Volume, \(V\) (ft³):

Example: 5000 ft³

Discharge Duration, \(\Delta t\) (s):

Example: 300 s
