Abstract

PURPOSE: To discharge influent water at an early date out of dam without influent water staying in the dam for an extended period of time as protection of dam water against its eutrophication.
CONSTITUTION: Temperature of influent water 1 at an upstream point of dam 2 is measured, while the vertical temperature distribution of dam water 2 is measured constantly. At the time of water discharge from the dam, the water-intake-gate 7 is moved to a certain depth of the dam water 2 so that it matches to the water layer where temperature is the same or nearly the same with that of influent water, and let the dam water 2 of the said temperature layer discharge out of the dam 2.
