Grain size distribution of armor layer

This dataset provides 4 sets of measured data on natural riverbed armoring (including 1 set of measured data from the lower reaches of the Danjiangkou Reservoir in China and 3 sets of measured data from the lower reaches of the Three Gorges Reservoir in China), as well as 9 sets of indoor flume test data. Specifically, this dataset includes: initial bed material grain size distribution, measured armoring layer grain size distribution, initial water depth for calculation, initial flow velocity, and energy slope.本数据集包含4组天然河床粗化（natural riverbed armoring）实测数据，其中1组采自中国丹江口水库下游，3组采自中国三峡水库下游，另包含9组室内水槽试验数据。具体而言，本数据集涵盖以下内容：初始床沙级配、实测粗化层级配、计算用初始水深、初始流速及能量坡度。
