Data underlying the publication: Study on the Migrating Speed of Free Alternate Bars

This dataset has been stored for the purpose of showing the data used in the drawings and results in the text of the current submission to <i>JGR:Earth Surface, entitled: Study on the Migrating Speed of Free Alternate Bars. </i><br>The object of this study is the migrating speed of alternate bars, and the objective is to understand the existence of spatial distribution of the migrating speed and the dominant physical quantity. Three research methods are used: flume experiments, numerical calculation on actual rivers, and theory. There are the 3-types data in this dataset. The data in the folder 'AppendixA', 'Flume_experiment_case1' and 'Flume_experiment_case2' were measured in July 2021 at the aurhor's experimental facility at Niigata University. The data in the folder 'Section 6' were obtained using the authors' calculation code. all data type are .csv<br>Please read README.md for the details.

本数据集用于呈现本次投稿至《地球物理研究杂志：地表》（JGR:Earth Surface）、题为《自由交错沙洲迁移速度研究》的论文中配图与正文结果所使用的全部相关数据。本研究的核心对象为自由交错沙洲的迁移速度，研究目标在于明确其迁移速度是否存在空间分布特征，并识别影响其迁移的主导物理量。本研究采用三类研究方法：水槽实验、天然河流数值计算与理论分析。本数据集共包含三类数据：其中，'AppendixA'、'Flume_experiment_case1'及'Flume_experiment_case2'文件夹内的数据，于2021年7月在作者位于新潟大学的实验设施中实测获得；'Section 6'文件夹内的数据则通过作者团队自研的计算代码生成。所有数据均采用.csv格式。详细信息请参阅README.md文件。
