SOLUTION OF RIVER JOINTS TAKING INTO CONSIDERATION SEDIMENT TRANSPORT MOVEMENT

Keywords: Keywords: sediment transport, flow, bifurcation of river, junction of river, roughness coefficient
Abstract: Calculation of junction and bifurcation river joints is complex problem because of necessity of fulfilling of both balance equations of water flow and stream intensity, for changing simultaneously hydraulic and sediment transport values. A trial of finding of satisfying and universal method that could be used for different river joints was taken up. In the first phase the bifurcation river joint was calculated. After water division flowing in arms of a river behind bifurcation, sediment transport parameters were determined. These parameters were changing in sorting process, that makes possible fulfilling of fundamental condition as the balance of sediment transport intensity. In the second phase calculated parameters were entered the calculation programs of junction river joints. The results of calculations in the form of curves of both stream intensity (as the function of water flow) and course of equivalent diameters, expressing new composition of sediment transport in arms of a river behind bifurcation or in a main river bed behind junction along with the change of roughness coefficient were finally presented.
