摘要

查看大幅下载幻灯片查看大幅下载幻灯片 关闭模版朝鲜半岛多山的地形给有效的水资源管理带来了挑战。值得注意的是,北汉江和临津江这两个重要的江河流域基本上都是发源于朝鲜的共享河流。在北朝鲜修建了各种水坝之后,每年有数十亿吨的水从北朝鲜这些河流的上游减少到南朝鲜。本研究对受到朝鲜大坝运行影响的两个主要河流流域进行了影响分析。在临南大坝运行前后,观察到月平均流入量显著减少(27.7%),韩国华川大坝的总泄洪量减少了 40.2%。对入流流量的分析表明,北朝鲜大坝的运行对满足位于北汉江和临津江流域的大坝的入流流量要求有很大影响。为了确保入流流量,这项研究提出了两个计划。第一个计划涉及利用北汉江流域的现有大坝,而第二个计划则建议将北朝鲜的大坝连接起来,同时考虑到共享的河流。

The Korean Peninsula's mountainous terrain poses challenges to effective water resource management. Notably, two significant river basins, North Han River and Imjin River basins, are essentially shared rivers originating in North Korea. After the construction of various dams in North Korea, billions of tons per year of water annually decreased from the upper reaches of these rivers of North Korea to South Korea. This study conducted an impact analysis on two major river basins affected by dam operations in North Korea. Both before and after the Imnam Dam operation, significant reduction (27.7%) in the average monthly inflow was observed, and the total release of the Hwacheon Dam in South Korea decreased by 40.2%. The analysis of instream flow indicated that the operation of dams in North Korea had a substantial impact on fulfilling instream flow requirements for dams located in North Han River and Imjin River basins. To ensure instream flow, this study proposed two plans. The first plan involved the utilization of existing dams in the North Han River basin, while the second plan suggested connecting the dams in North Korea, taking into account the shared rivers.

期刊介绍: Hydrology Research provides international coverage on all aspects of hydrology in its widest sense, and welcomes the submission of papers from across the subject. While emphasis is placed on studies of the hydrological cycle, the Journal also covers the physics and chemistry of water. Hydrology Research is intended to be a link between basic hydrological research and the practical application of scientific results within the broad field of water management.
