What is an Acre-Foot of Water?

An acre-foot of water is a unit of volume commonly used in the United States in reference to large-scale water resources, such as reservoirs, aqueducts, canals, sewer flow capacity, irrigation water, and river flows. It is defined as the volume of one acre of surface area to a depth of one foot. This is equivalent to exactly 43,560 cubic feet, approximately 325,851.4 US gallons, or approximately 1,233.5 cubic meters. This measurement is typically used in the context of water supply and usage, and it provides a standardized method of assessing the amount of water available or required for various purposes, such as agricultural irrigation, municipal water supply, or industrial processes.

Example Calculation 1

Let's assume the following values:

Using the formula:

\[ V = \frac{100 \times 200 \times 5}{43560} = \frac{100000}{43560} \approx 2.2957 \]

The volume of water is approximately 2.2957 acre-ft.

Example Calculation 2

Let's assume the following values:

Using the formula:

\[ V = \frac{150 \times 250 \times 4}{43560} = \frac{150000}{43560} \approx 3.4436 \]

The volume of water is approximately 3.4436 acre-ft.
