Streamflow droughts and floods in the US between 1970-2022

This dataset contains streamflow drought and flood events for 1002 gauging stations in the Contiguous United States between 1970 and 2022. Drought and floods were identified using methodology outlined in Götte & Brunner (2024) and are characterized by there start and end date. The dataset accompanies the paper \"Hydrological drought-to-flood transitions across different hydroclimates in the United States\" by Götte & Brunner published in Water Resources Research under DOI 10.1029/2023WR036504.本数据集涵盖1970年至2022年间美国本土（Contiguous United States）内1002个水文测站（gauging stations）的径流干旱（streamflow drought）与洪水事件。干旱与洪水事件采用Götte与Brunner（2024）提出的方法识别，并以事件的起止日期作为核心特征。本数据集为Götte与Brunner发表于《水资源研究》（Water Resources Research）、DOI为10.1029/2023WR036504的论文《美国不同水文气候区的水文干旱-洪水转换过程》提供配套支撑。
