The Flood Water Volume calculator computes the volume of water covering an area at an approximate average depth.
Instructions: Choose units and enter the following:
Volume of Water (V): The calculator returns the approximate volume of water on the area in Acre-Feet, gallons and cubic meters. However, these can be automatically converted to other volume units (e.g. liters, cubic yards) via the pull-down menu.
A simple formula for volume is:
V = A * d
where:
This Flood Water Volume uses this formula. Note: this does not take into account the natural slope on the edge that is usually the case with bodies of water such as ponds and lakes. Nonetheless, this can be a useful tool if the area is significant.
