Supporting data for PhD dissertation: Tracking dunes: On the morphology, interactions and sediment fluxes associated with multi-scale river dunes.

This data set provided the supporting data for Chapter 6 in the PhD dissertation Tracking dunes: On the morphology, interactions and sediment fluxes associated with multi-scale river dunes by J. Y. Zomer.<br>A unique and extensive series of field campaigns in an alluvial lowland river enables tracking two distinct dune scales that coexist, and both actively migrate. The field campaign has been designed to track both primary and secondary dunes, which migrate at different timescales. The data set also included flow velocity measurements (ADCP), information on grain size distributions of the bed material (based on bed samples), suspended sediment concentration (based on water samples) and grain size distribution of the suspended sediments.<br>

本数据集为J. Y. Zomer所著博士学位论文《追踪沙丘：多尺度河流沙丘的形态、相互作用与泥沙通量》的第六章提供支撑数据。
研究团队在冲积平原河流中开展了一系列独具特色且规模庞大的野外实地勘测工作，得以对两种共存且均能主动迁移的不同尺度河流沙丘进行追踪。本次野外勘测的设计初衷为同步追踪初级沙丘与次级沙丘，二者以截然不同的时间尺度完成迁移过程。本数据集还涵盖了基于声学多普勒流速剖面仪（ADCP）获取的实测流速数据、通过河床采样得到的河床泥沙级配信息、基于水样分析获得的悬沙浓度数据，以及悬移质泥沙的级配分布特征。
