Data supplement to "How debris-flow composition affects bed erosion quantity and mechanisms - an experimental assessment"

Data was generated for 98 debris flow erosion experiments in a 5.4 m long flume with an erodible loosely packed sediment bed. In the 98 experiments the bed conditions were kept constant, but the composition of the debris flow changed. Volume, water content, gravel content and clay content were varied. The paper contains all information on procedures, settings, sensors and data analyses. The data in this supplement contains the DEMs of the erodible bed, the data of the sensors in the flume and an overview of all experiments.

本数据集源于针对长5.4米的可侵蚀松散堆积泥沙床水槽开展的98组泥石流侵蚀实验所生成的数据。在全部98组实验中，水槽床面条件始终保持恒定，仅改变泥石流的组分，实验调控变量包括体积、含水率、砾石含量与黏土含量。相关论文中包含了实验流程、参数设置、传感器配置方案以及数据分析的全部细节信息。本补充材料所附数据集包含可侵蚀床面的数字高程模型（DEM, Digital Elevation Model）、水槽内置传感器的实测数据，以及所有实验的汇总概览。
