Water Quality Volume Calculator

Formula

The formula to calculate the Water Quality Volume (WQV) is:

\[ WQV = P \cdot A \cdot Rv \]

Where:

\(WQV\) is the Water Quality Volume (acre-inch)
\(P\) is the precipitation depth (inches)
\(A\) is the watershed area (acres)
\(Rv\) is the runoff coefficient

Water Quality Volume Definition

Water Quality Volume (WQV) is the volume of water that needs to be managed to maintain water quality standards. It is calculated by multiplying the precipitation depth, watershed area, and runoff coefficient together.

Example Calculation

Let's assume the following values:

Precipitation Depth (P) = 1 inch
Watershed Area (A) = 100 acres
Runoff Coefficient (Rv) = 0.3

Using the formula to calculate the Water Quality Volume (WQV):

\[ WQV = 1 \cdot 100 \cdot 0.3 = 30 \]

The Water Quality Volume (WQV) is 30 acre-inch.
