Data underlying the publication: Comparing Global Violations of Environmentally Critical Groundwater Discharge Thresholds

We conducted a global comparison of three methods of estimating environmentally critical flow over the historic period 1960-2010 to evaluate the influence of including groundwater contributions to streamflow in global environmental flow assessments. This methodological study uses modelled groundwater discharge and streamflow data from natural and human-impacted runs to calculate environmental flow thresholds and violations of these thresholds. The data provided here has been processed from the monthly, gridded, simulated output to river basin scales. The analyses were performed using R, and thus the data included here is meant to be assessed in the same manner.

本研究针对1960-2010年历史时段内的三种环境临界流量估算方法开展全球对比，旨在评估全球环境流量评估中纳入地下水对河道径流的贡献所产生的影响。本项方法学研究采用自然与受人类活动影响的水文模拟试验所产出的地下水排泄量与河道径流量数据，用于计算环境流量阈值及阈值突破情况。本次发布的数据集已由逐月格点化模拟输出结果处理至流域尺度。本研究采用R语言完成全部分析流程，因此本次提供的数据集需以相同方式进行评估。
