The research used Fuzzy Logic algorithm based on the rule, the principle of "IF - THEN" and built the membership functions for the input variables: water level, inflow to the reservoir, the water demands, and discharge from the reservoir. | MINISTRY OF AGRICULTURE AND RURAL DEVELOPMENT WATER RESOURCES UNIVERSITY ************** OPTIMAL RESERVOIR OPERATION FOR WATER SUPPLY IN DRY SEASON: THE CASE STUDY OF CUA DAT RESERVOIR IN THE MA-CHU RIVER BASIN TRINH XUAN MANH MSc Thesis September 2014 Optimal reservoir operation for water supply in dry season: the case study of Cua Dat reservoir in the Ma – Chu river basin Master of science thesis By Trinh Xuan Manh Supervisor Dr. Nguyen Mai Dang (WRU) Mentors HA NOI September 2014 This research is finished for the partial fulfillment of requirements for the Master of science degree at Water Resources University, Ha Noi, Viet Nam i Abstract Water supply of reservoirs and especially reservoirs used for irrigation, hydropower, aquaculture, navigation, environment in the dry season are often troubled due to increasing water demands according to the economic development and society, while the flow to the reservoir is limited. In recent years, the depletion of the river flow during the dry season occurs more frequently and at a more intense level. This is partly due to forest coverage reduction in the upstream of river basins, and partly due to the effects of climate change. Hence, computation of the optimum water supply of reservoir for the water demands in the dry season is needed. This study presents the initial research on applying Fuzzy Logic Algorithm for optimal operation of water supply in the dry season of 2011-2012 of the Cua Dat Reservoir in the Chu River basin, Thanh Hoa province. The Cua Dat Reservoir is a multi-purpose reservoir for the following tasks: flood prevention, water supply, irrigation, power generation, and environmental flows. In addition, MIKE 11 model is also used to simulate the release from the reservoir to the downstream to evaluate the efficiency of the optimal method. The research used Fuzzy Logic algorithm based on the rule, the principle of "IF - THEN" and built the membership functions for the input variables: water .
