通过室内模型试验研究生态植草边沟内的水流特性,对5组不同流量下的植草边沟与非植草边沟进行了较为系统的研究,然后通过试验数据结合水力学分析,得出结果:植草边沟内的水流在缓流情况下,其粗糙系数为0.03;同时,边沟内的植草在很大程度上改变了原来水流的内部结构,较混凝土边沟的沟渠糙率增大,流速减小,水位升高。 Through the indoor model test to study the water flow characteristics in the eco-grass ditch, five groups of grass ditch and non-grass ditch at different flow rates were systematically studied. Then, the experimental data and hydraulics analysis showed that the grass flowering In the case of slow flow, the roughness coefficient of the water flow in the ditch is 0.03; meanwhile, the vegetation in the ditch greatly changes the internal structure of the original water flow, and the roughness of the ditch is larger than that of the concrete ditch, Small, rising water level.
