Data underlying the publication: 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: 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《地球物理学研究杂志：地表》（JGR:Earth Surface）、题为《自由交替沙洲迁移速率》（The Migrating Speed of Free Alternate Bars）的论文中配图与正文结果所依托的实验数据。本研究的核心对象为交替沙洲的迁移速率，研究目标为明确该迁移速率的空间分布规律及其主导物理量。本研究采用三类研究手段：水槽实验、天然河道数值计算与理论分析。本数据集共包含三类数据：'AppendixA'、'Flume_experiment_case1'与'Flume_experiment_case2'文件夹内的数据，均于2021年7月在新潟大学作者的实验平台中测得；'Section 6'文件夹内的数据则通过作者团队自研的计算程序生成。所有数据的格式均为.csv文件。详细信息请参阅README.md文件。
