Peak Discharge (Q<sub>p</sub>) Calculator by Tabular Hydrograph Method

Peak Discharge (Q_p) Calculator

Calculate the peak discharge using the Tabular Hydrograph Method (triangular hydrograph approximation):
\[ Q_p = \frac{2V}{T \times 60} \]

* Enter the total runoff volume \(V\) (ft³) and the runoff duration \(T\) (minutes).

Step 1: Enter Parameters

Total Runoff Volume, \( V \) (ft³):

Example: 5000 ft³

Runoff Duration, \( T \) (minutes):

Example: 30 minutes
