  • Patent number: 11866897
    Abstract: A main stream reservoir ecological modulation method considering incoming water from interval tributaries is provided. The method determines the contribution ratio of the incoming water from interval tributaries to first-day's water rising in a high-flow surge process and when to start ecological modulations of spawning ground sections, determines a river course routing method after a main stream and its tributaries joining and calibrating parameters, based on past hydrological data, performing river flow calculation on the discharge volume of upstream reservoirs and the flow after interval tributaries joining, and determines a main stream reservoir ecological modulation mode considering incoming water from interval tributaries.
