การปฏิบัติการระบบอ่างเก็บน้ำแบบหลายอ่างเพื่อความต้องการน้ำอเนกประสงค์ในลุ่มน้ำแม่กลอง

Abstract

The multiple reservoir system operation model was developed for the Mae Klong River Basin, Thailand using the daily reservoir data during 2002-2013. The objective of this study was to simulate the complex reservoir operation system and to propose the water allocation concept of joint operation of reservoirs in the different manners. The simulation run covered as follows; dam-reservoir system constructed completely and used in the existing time and planned to construct in future, reservoir rule curves currently employed, water allocation concepts newly proposed such as (1) Fractional Water Allocation, (2) Capacity Sharing Concept, and (3) Adjusted Storage Ratio, determination of release coefficient which some shortage was allowed during the critical drawdown period, as well as the operating policy at Mae Klong Dam by using simple rules. The results obtained from the operation model could help create guidance especially for the reservoir operators at EGAT and RID offices to determine the released water accordingly to the water availability and to enhance effectiveness in supplying water to satisfy multi-sectoral water uses in the Mae Klong River Basin.
