Annual maximum reservoir inflow records for Shimen, Feicui, Zengwen and Wushantou (2000-2025).

This repository includes annual maximum reservoir inflow records for Shimen, Feicui, Zengwen and Wushantou Reservoirs in Taiwan for the period 2000-2025, together with the QGIS and MATLAB scripts used for mapping, data processing, and flood-frequency analysis. The inflow series were compiled from the Water Resources Agency, Ministry of Economic Affairs, Taiwan, and linked to major typhoon events using Central Weather Administration records where available. Each file provides, for each reservoir and year, the annual maximum inflow (m³/s), the date of the maximum event, and the associated typhoon name when identified. The dataset supports uncertainty-aware flood-frequency analysis of annual-maximum inflows, including stationary and non-stationary fits of Gumbel, Log-Pearson Type III, and generalized extreme value models, as well as bootstrap- and simulation-based uncertainty quantification reported in the associated manuscript. No personal or sensitive data are included.本数据仓库收录中国台湾地区石门、翡翠、曾文及乌山头水库2000年至2025年的年度最大入库流量记录，以及用于绘图、数据处理与洪水频率分析的QGIS脚本与MATLAB脚本。该批流量序列由中国台湾地区经济事务部门水资源署整编而成，并在数据可用时通过中央气象署的观测记录关联至对应的重大台风事件。每个数据文件将按水库与年份维度，提供年度最大入库流量（单位：立方米每秒）、极值流量事件的发生日期，以及经识别后的关联台风名称。本数据集可支撑年度最大入库流量的不确定性感知洪水频率分析，涵盖冈比分布（Gumbel）、对数皮尔逊III型分布（Log-Pearson Type III）及广义极值分布（generalized extreme value）的平稳与非平稳拟合，同时支持关联研究论文中提及的基于自举法（bootstrap）与模拟方法的不确定性量化分析。本数据集未包含任何个人信息或敏感数据。
