Equation of Sediment Transport for Slope Flows

摘要

The suggested model of transporting capacity for slope flows is based on the laws of physics and hydrodynamics In this model, the probability constituent plays an important role for different types of sediment movement within the range of velocities close to critical values. Each type of movement is specified by an individual transportation coefficient independent of the sediment's particle size. The model has been parameterized and verified using a large amount of the authors' experimental results on the determination of transport capacity within a wide range of slope gradients (0-30%), as well as using the data obtained by Goncharov. The correlation coefficients are high (0.90-0.98), with the maximal relative errors fluctuating within 15-35%.
