This study aims to provide a practically efficient approach for determining the most efficient joint operation rule for two reservoirs connected by a waterway tunnel. For this purpose, the connecting tunnel’s effect was assessed and three heuristic joint operation rules accounting for the connecting tunnel were evaluated. A standard operation policy with the connecting tunnel led to positive effects on the water resource system of the target basin with regard to a reliable water supply. The connecting tunnel provides an additional water supply of 12.4 million m/year to the basin, and the reliability of the two reservoirs increased. Among the three rules, the equivalent reservoir (ER) rule led to the most positive effect on water supply. We found that the ER rule could maximize the positive effects of the connecting tunnel by maintaining the effective water storage rates of the two reservoirs. Moreover, the effects of hydrologic uncertainty on the joint operation rules were discussed using the synthetically generated multiple streamflow traces.

评估连接两座多用途大坝之间隧道的联合操作规则

本研究旨在提供一种实用有效的方法，以确定通过水道隧道连接的两个水库的最有效联合运行规则。为此，对连接隧道的效果进行了评估，并对考虑连接隧道的三个启发式联合操作规则进行了评估。连接隧道的规范运营政策对目标流域的水资源系统产生了积极影响，确保供水可靠。连接隧道为流域提供了 1240 万立方米/年的额外供水，提高了两个水库的可靠性。在这三个规则中，等效水库（ER）规则对供水产生了最积极的影响。我们发现 ER 规则可以通过保持两个水库的有效蓄水率来最大化连接隧道的积极影响。此外，使用综合生成的多条水流轨迹讨论了水文不确定性对联合操作规则的影响。这是一篇根据知识共享署名许可 (CC BY 4.0) 条款分发的开放获取文章，该许可允许复制、改编和重新分发，前提是正确引用原始作品 (http://creativecommons.org/licenses/by/ 4.0/)。doi: 10.2166/nh.2020.053 s://iwaponline.com/hr/article-pdf/doi/10.2166/nh.2020.053/648060/nh2020053.pdf Ji Woo Jeong Nakdonggang Weir Office, Dae7 South Korea, K-42 Young-Oh Kim 土木与环境工程系，首尔国立大学，首尔 08826，
