- Abstract
In order to improve the research on the mathematical model of sediment-laden river, firstly, according to the difference of Bingham shear stress in the rheological equation, the hyper-concentration flow and lower-concentration flow were distinguished and the necessity of using the coupling solution of flow field and sand field for the hyper-concentration flood was demonstrated. Secondly, according to the comparison and analysis of several sand-carrying force formulas and measured results, the results showed that Dou Guoren’s formula could be suitable for both hyper-concentration flow and lower-concentration flow at the same time and the nesting of the formula in the mathematical model calculation was realized. On this basis, the software of water and sediment mathematical model was developed and the calculated results were presented to users intuitively through scheme management and dynamic demonstration, which was convenient for non-sediment professionals. Finally, taking the actual occurred flood in the channel of the Yellow River near Huayuankou on August 1996 as an example, it calculated the flow field and tested the applicability of the software.
