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>
