Incipient Motion Experiment of Sediment in Silty-Sand Coast
Sediment issues, especially the channel siltation issues in silty-sand Coast are becoming more and more prominent as the development of harbor construction in silty-sand coasts. In order to learn the incipient motion characteristics under influence of wave, current and wave-current combination of sediment in silty-sand coasts, provide necessary parameters for engineering analysis of fluvial process and mathematical model analysis, and then provide science and technology fundamentals for harbor construction, experiments are carried out with samples from the under construction Haiyanghong port area in Dandong. Under the same condition, when the initial sediment density, which is of great influence on incipient motion, is larger, the incipient motion is harder to occur; and wave is the main hydrodynamic force to devote to sediment incipient motion. Generally, sediment in silty-sand coasts shows the characteristic of silt. However, fine sediment rises obviously in the experiment and the water gets muddy very easily as the existence of a certain amount of clay.
