Triangle Hydrograph Method Calculator

Calculate the peak discharge using a triangular hydrograph:
\( V = \frac{Q_p \times T}{2} \) → \( Q_p = \frac{2V}{T} \)

* Enter the runoff volume (ft³) and hydrograph duration (s).

Step 1: Enter Parameters

Runoff Volume, \(V\) (ft³):

Example: 10,000 ft³

Hydrograph Duration, \(T\) (s):

Example: 1800 seconds (30 minutes)
