Anonymized Daily Groundwater-Level Dataset for the July 2023 Extreme Rainfall Event in the North China Plain Alluvial–Diluvial Fan Aquifer

This dataset contains anonymized daily groundwater-level observations from shallow monitoring wells in the piedmont alluvial–diluvial fan area of the North China Plain during the July 2023 extreme rainfall event. The dataset covers a 50-day event window from 20 July to 7 September 2023 and was used to analyze event-scale groundwater-level response trajectories.本数据集包含2023年7月极端降雨事件期间，华北平原山前冲洪积扇区浅层监测井的匿名化每日地下水位观测数据。该数据集覆盖2023年7月20日至9月7日共50天的事件观测窗口，用于分析事件尺度下的地下水位响应轨迹。
