Understanding the impact of human-made structures on groundwater levels is crucial, with structures like dams or weirs presenting both challenges and opportunities for study. The Baekje weir in South Korea offers an unique case as it has undergone full gate openings, a condition not typically observed in weirs and reservoirs, providing a unique opportunity to simulate conditions resembling weir removal. The primary objectives include investigating groundwater level fluctuations influenced by various weir operations, proximity to the weir, and seasonal variations. The study employs observed data to simulate conditions both with and without the weir, encompassing scenarios of full gate opening. This research is part of the submission WaterResourcesResearch2022WR032779RRRR to the journal Water Resources Research, aiming to deepen our understanding of how such structures impact water resources.

明晰人工构筑物对地下水位的影响机制具有重要学术意义，大坝（dam）、堰（weir）等人工构筑物既是相关研究的核心对象，也为研究工作带来了独特挑战与机遇。韩国百济堰（Baekje weir）便是极具研究价值的典型案例：该堰曾实施全闸开启工况，而这类工况在常规堰闸与水库中较为罕见，这为模拟堰闸拆除后的水文环境提供了绝佳契机。本研究的核心目标在于探究不同堰闸调度方案、与堰闸的空间距离以及季节变化对地下水位波动的影响。研究采用实测数据，分别模拟了存在堰闸与无堰闸两种场景下的水文条件，其中涵盖全闸开启工况。本研究作为投稿至《Water Resources Research》期刊的稿件WaterResourcesResearch2022WR032779RRRR的组成部分，旨在深化对这类人工构筑物如何影响水资源系统的认知。
