项目摘要

Recently, river improvement should be planned to refine various functional aspects of rivers such as flood control, more efficient water resources utilization, recreational or leisure usage of rivers, well-conserved ecological situation, aquatic habitat and so on. As a compromise, erosion-protection works of flood plain and/or side slope of levee (embankment) by vegetation cover was investigated instead of more rigid protection works.When the sand bed is covered by vegetation layr, the Reynolds stress in the vegetation layr is effectively suppressed due to drag by vegetation. The flow with vegetation was described numerically by taking account of the effect of vegetation. In case of flexible vegetation, the deformation of individual plants and the flow over deformed vegetation layr were solved simultaneously. The method how to measure the flexural rigidity, which governs the deformation of the plants, in the fields was also studied.Furthermore, the effects of geometry of cross-section, which often have flood plain and side slopes, on the erosion-protection efficiency of vegetation layr were investigated by using the three-dimensional numerical analysis of flow with vegetation. The results of calculation obtained by changing the parameters systematically were summarized to be conveniently used for design of erosion-protection works with vegetation cover.
近期,我们应规划改善河道,以改善河道的各种功能,例如防洪、更有效地利用水资源、河道的康乐或消闲用途、妥善保育的生态环境、水生生物栖息地等。作为折衷方案,河漫滩和/或堤防边坡的防冲工程当砂床被植被层覆盖时,植被层的阻力作用有效地抑制了植被层中的雷诺应力。考虑植被的影响,对有植被的水流进行了数值模拟。在柔性植被情况下,同时求解了植物个体的变形和变形植被层上的水流。本文还研究了在野外条件下植被抗弯刚度的测定方法,并通过有植被水流的三维数值模拟,研究了断面形状对植被层防冲效果的影响。总结了系统地改变参数的计算结果,以便于植被防冲工程的设计。
