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

Upstream Area, \(A_1\) (ft²):

Example: 1000 ft²

Downstream Area, \(A_2\) (ft²):

Example: 500 ft²

Pond Length, \(L\) (ft):

Example: 50 ft
