Description

technical field [0001] The invention belongs to the field of basic research on river dynamics and movement of moving matter, and in particular relates to a model test device for sorting a vertical section of moving matter on a river bed and a method for using the same. It is mainly applicable to technical fields such as particle separation tests of river moving mass, and can be extended to other research fields of particle separation of solid-liquid two-phase flow. Background technique [0002] In the field of river dynamics research, the vertical distribution characteristics of riverbed sections are the important basis and core elements of river sediment movement theory, riverbed morphology research, and river engineering construction design. The model test of vertical separation of bed mass is one of the most effective and important means to understand and master the characteristics of the vertical section of the river bed in the river channel; the current conventional tes...
