Consumptive uses alter the hydrologic cycle and may modify the environment. Because the same drop (or even the same molecule) of water can be reused many times by humans and also is needed to maintain environmental integrity, conflicts between different uses are frequent.
C consumptive use (of water)
Definition (english only)
Water abstracted which is no longer available for use because it has evaporated, transpired, been incorporated into products and crops, or consumed by man or livestock.
delivery/release The amount of water delivered to the point of use and the amount released after use; the difference between these amounts is usually the same as the consumptive use. See also consumptive use.
