| Description: | Interactive tutorial with calculator to teach the various units and schemes for describing volumes of water. "Precipitation is often spread over a large area as in a rainstorm. Rather than describe the total volume of water in a rainstorm in terms of how many gallons fell, the equivalent depth is typically used. This is the average depth of the rain over the area where the rain fell. Area inches are used on TV and in the newspaper to describe a rain. Snow is also described with area depth units "as there was a 6 inch snow last night" or "there was a 1 and 1/2 foot snowstorm over the weekend". Cubic volume units, such as gallons, cubic feet and acre-feet are computed from the depth units by multiplying them by the area over which the rain (or snow) occurred. (When snow is melted, there is roughly 1 inch of water for each 10-inches depth of snow.) The volume of water in a rainstorm as well as the water stored in a lake or reservoir can be in millions and millions of gallons. Similarly the volume of water that flows past a point on a large riverbank in a day is very large. Larger units are needed to simplify the description of large volumes of water. One unit that has been used to do this is the acre-foot." |
