Global meta-analysis of published river bank erosion and migration rates

This dataset is a compilation of 993 measurements of riverbank erosion or migration rates from 336 rivers and streams compiled from 169 published English language studies. The dataset spans rivers across latitudes ranging from 46 deg south to 71 deg north. The rivers range in drainage area from 0.6 to 3 million square kilometers. If provided in a published study, recorded channel width, river drainage area, and sediment load and/or yield were summarized. In the absence of these ancillary data from the original source, this data was compiled from other published studies, global and regional datasets, or measured from Google Earth images. The dataset also provides information on whether the rates were measured at an individual river bend or represent reach-based averages, as well as, whether the river is single or multi-threaded. Revisions 2023 January update Added 72 new erosion measurements. Dropped 10 records that did not have mean erosion values. “DrainageArea(km^2)_rabpro” added “DrainageArea(km^2)” – updated to only include published drainage area and values obtained from sources other than the rabpro analysis. “River_slope_pub” added to provide river slope values provided in the published erosion study or other source listed in the “Slope Reference” field “RiverSlope_Lin” added “FLO1K_MonthlyMax_LT” and “FLO1K_MontlyMax_PoR” added “KG_Zone” added from Köppen-geiger climate classification based on Beck et al. 2018本数据集整合了来自169篇已发表英文文献中336条河流与溪流的993组河岸侵蚀或迁移速率测量数据。数据集覆盖的河流纬度跨度为南纬46°至北纬71°，流域面积介于0.6至300万平方千米之间。若原始已发表研究中提供了相关辅助数据，则会汇总记录的河道宽度、河流流域面积以及泥沙负荷和/或产沙量；若原始文献未提供此类数据，则从其他已发表研究、全球或区域数据集获取相关信息，或通过Google Earth影像进行测量提取。本数据集还会标注速率测量是针对单个河湾，还是基于河段的平均值，同时标注河流为单河道还是多河道型。2023年1月修订版更新内容如下：新增72组侵蚀速率测量数据，删除10条未包含平均侵蚀值的记录；新增"DrainageArea(km²)_rabpro"字段，并补充"DrainageArea(km²)"字段，更新后仅纳入已发表的流域面积数据以及非rabpro分析获取的流域面积数值；新增"River_slope_pub"字段，用于提供已发表侵蚀研究或"Slope Reference"字段中提及的其他来源所给出的河流坡度值；新增"RiverSlope_Lin"字段；新增"FLO1K_MonthlyMax_LT"与"FLO1K_MontlyMax_PoR"字段；新增"KG_Zone"字段，该字段基于Beck等人2018年的研究，由柯本-盖格（Köppen-geiger）气候分类系统生成。
