Dependence of saltation characteristics on bed organisation in numerical simulation

Original language description

The present paper addresses the issue of saltation motion (one type of bed-load motion) that further may be used for prediction of sediment transport (formation of river beds, coastlines, pipe granular bed, etc.). The numerical approach used there is based on two components: the Lagrangian description of the suspended particles and a simulation of the interactions of suspended and bed particles. The novelty of the paper is a bed model. It is supposed that theoretical bed layer consists of identical spherical particles distributed in space in a special way. The offered bed model is used for the simulation of saltation motion in a turbulent stream. The influence of bed structure (diameter of bed particles and bed porosity) on saltation parameters (average length and height of one jump) is studied here. A comparison of saltation parameters with corresponding experimental parameters from literature was made.
