Response of flow and saltating particle characteristics to bed roughness and particle spatial density

The data were used in the paper "Response of flow and saltating particle characteristics to bed roughness and particle spatial density" which was submitted to "Journal of Geophysical Research-Earth Surface". In this paper, the effects of bed roughness and particle spatial density on the bedload transport are investigated by numerical simulations. The distributions of key parameters for saltation, including their changes, are assessed using the PDF curves. It is found that bed roughness is likely composed of particles of equivalent size for fine particles.

本数据集用于提交至《地球物理研究杂志-地表》（Journal of Geophysical Research-Earth Surface）的论文《水流与跃移颗粒特征对床面粗糙度及颗粒空间密度的响应》。该研究通过数值模拟方法，探究了床面粗糙度与颗粒空间密度对推移质输运过程的影响。本研究采用概率密度函数（Probability Density Function, PDF）曲线，对跃移过程关键参数的分布特征及其变化规律进行了评估。研究发现，对于细颗粒而言，床面粗糙度大概率由等效粒径一致的颗粒构成。
