Investigations of Continuous Bed Load Saltating Process

摘要: Particle saltating motions during bed load transport are dominated by the forces acting upon particles and random process of impacting on rebounding from channel bed. A real-time flow visualization technique is developed in this study to measure particle trajectories, corresponding velocities, angles. Based experimental data, regression equations for dimensionless length, height, velocity were obtained. numerical model that able simulate continuous a single was developed. The calibrated verified with results satisfactory. also used generate series synthetic data. these data flume collected previous investigators, equation derived.
