Laboratory measurement of wave-current ripple development

Large-scale flume experiments were conducted in the Total Environment Simulator at the University of Hull in order to study ripple dynamics in mixed sand–clay substrates under combined flows. This dataset provides detailed information of wave-current ripple development, recording by Ultrasonic Range System (URS), from beds with the initial clay content between 0% and 12.3%. In addition, the results of grain size analysis, using Malvern Mastersizer 2000, from sediment cores collected during the experiments are included, showing vertical change in clay content with ripple evolution. Moreover, hydrodynamic data including near-bed flow velocities monitored by Vectrino Profilers and water surface elevation recorded by acoustic water level sensors are also in the present dataset.

本研究于赫尔大学（University of Hull）全环境模拟舱（Total Environment Simulator）内开展大型水槽实验，旨在探究复合流作用下砂泥混合底床的沙纹动力学特性。本数据集收录了由超声测距系统（Ultrasonic Range System，URS）记录的波流共同作用下沙纹发育的详细数据，实验所用底床初始黏土含量介于0%至12.3%之间。此外，数据集还包含实验期间采集的沉积物岩心的粒度分析结果——该分析采用马尔文Mastersizer 2000粒度分析仪完成，结果清晰展现了随沙纹演化过程中黏土含量的垂向变化特征。本数据集同时涵盖水动力数据，包括由Vectrino剖面流速仪（Vectrino Profilers）监测得到的近底流速，以及声学水位传感器记录的水面高程信息。
