Retention cum Detention Pond Storage Volume Calculator

Pond Storage Volume Calculator

Calculate the storage volume of a retention cum detention pond using the Double-End Area Method:
\[ V = \frac{A_1 + A_2}{2} \times L \]

* Enter the upstream area \(A_1\) (ft²), downstream area \(A_2\) (ft²), and pond length \(L\) (ft).

Step 1: Enter Parameters

Example: 1000 ft²

Example: 500 ft²

Example: 50 ft

Formula: \[ V = \frac{A_1 + A_2}{2} \times L \] with \(V\) in ft³.
