Supporting data for the publication: Evidence of secondary bedform controls on river dune migration

<em>The dataset contains supporting data for the publication </em>Evidence of secondary bedform controls on river dune migration <em>by Zomer, J.Y. and Hoitink, A.J.F. The objective of the study was to investigate the interaction between primary and secondary river dunes and their contribution to the total sediment transport flux. </em><em>The dataset includes river bed elevation data (acquired through multibeam echosounding) and bed grain size data based on river bed samples. </em><em>The data was acquired between 7 January 2022 and 25 February 2022 in the river Waal.</em>

本数据集为Zomer, J.Y.与Hoitink, A.J.F.发表的论文《次级底形调控河流沙丘迁移的证据》（Evidence of secondary bedform controls on river dune migration）提供支撑数据。该研究旨在探究初级与次级河流沙丘之间的相互作用，及其对总输沙通量的贡献。该数据集包含通过多波束测深（multibeam echosounding）获取的河床高程数据，以及基于河床采样得到的床面粒度（bed grain size）数据。所有数据采集于2022年1月7日至2022年2月25日期间的瓦尔河（Waal）。
