低水時における実時間ダム貯水池操作のシステム論的研究

Abstract

The aim of this study is to establish the real time operational policy of dam reservoir systemfor no rainfall periods between neighbouring floods.According to the control objectives, dam operational system is divided into four sub-systems, such as I) storage control where the storage volume will be lowered into the volume of low flowcontrol, ii) low flow control argumenting the quantity and improving the quality of releasedischarge, iii) turbidity control preventing the duration days of high concentration turbidityof release discharge from becoming longer, and iv) drought control dealing with the case wherethere is not enough flow discharge to satisfy the water demand. Then, in each sub-system, weconstruct the operational procedures and formulate the system equations. Concretely, first partis handling of meteological information data, second part is prediction of quality and quantity, and third part is decision of release discharge satisfying the control objective.Lastly, we apply the above methodology to the real river basin.
