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>

本数据集包含Zomer, J.Y.与Hoitink, A.J.F.所著论文《河流沙丘迁移中次级床形控制作用的证据》的支撑数据。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。数据集包含河床高程数据（通过多波束回声测深（multibeam echosounding）获取）及基于河床样本的床沙粒度数据。数据采集于2022年1月7日至2月25日期间，地点为瓦尔河（Waal）。
