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.
