Abstract
The issue of the research – investigation of the hydrodynamics of river sediments’ artificial structures in the interfluve of the Lo and the Kau rivers (The Northern Vietnam) as a tool for the formation of hydrodynamic and geochemical anomalies in water bodies. Laboratory studies of the speeds of movement and sedimentation of suspended sediments were carried out according to the planning of the experiment for a series of using natural and artificial crossbars in modeling the processes of transport and sedimentation of sediments. Based on a laboratory model experiment, the parameters of crossbars at different flow rates are considered for conditions of uniform movement of water in the tray and condition of sedimentation. Graphs of the dependences of the velocities of movement and sediment deposition are drawn, and the parameters of vortex flows in the zone before and after the crossbars are considered. Based on the results of laboratory modeling, graphs of the dependence of the characteristics of the transit and deposition of sediment, taking into account the influence of crossbars, are drawn. The obtained results of laboratory modeling provide data for planning further laboratory and field experiments on the transit of sediment with fertile silt, the accumulation of sediment in the riverbed and the influence of natural and artificial crossbars on sediment deposition, as well as for the formation of mobile sediment-retaining dams. The experiment was planned according to the Shenk X method. The results of the experiment were processed in MathCad and Solidworks.
