本研究第一年之研究內容擬以多水庫聯合操作為出發點，利用特定點規線訂定法配合遺傳演算法建立多水庫聯合操作規線優選模式，並以淡水河流域之石門水庫與翡翠水庫聯合操作系統為研究案例，制定出多水庫聯合操作之操作規線。根據目前結果顯示，石門水庫在聯合操作狀態下，藉由翡翠水庫的支援，利用聯合操作規線供水可比原單獨操作規線維持較穩定之蓄水位；翡翠水庫在聯合操作狀態下，因支援板新水廠部分水源量後其供水負擔增加，根據翡翠水庫聯合操作規線供水時，所維持之水庫蓄水位會略低於現行規線，而當水文條件較枯旱時，則必須於豐水期時抬高水位以確保能穩定供水。In practice, “rule curves” generally regulates reservoir operations. In an area of uneven water distribution, reservoirs can stabilize the water flow to mitigate water problems of floods or droughts. Therefore, a task to operate reservoirs efficiently is essential. However no single model, such as optimization or simulation, is available to solve all problems. In this study, a GA-based simulation is presented to develop the joint rule curves of multiple reservoir systems. A real two-parallel-reservoir system, the Feitsui and Shihmen reservoir system in northern Taiwan, is selected to demonstrate its applicability of the GA-based simulation model on a complex water resource system.
