近底流 meaning in English

near-bottom current

Compared with measured data , this equation can describe the sediment concentration distribution better both in main flow region and near - bottom region
与实测资料对比表明，该公式能更好地描述包含主流区与近底流区在内的泥沙含量分布规律。
Based on the analysis of characteristics of sediment particle concentration distribution , it is pointed out that the diffusion theory can describe sediment concentration distribution in main flow region but cannot explain sediment concentration distribution law near bottom because of the existence of sediment colliding shear stress
摘要在分析泥沙颗粒含量分布特性的基础上，指出扩散理论能较好地描述主流区的泥沙含量分布规律，但在近底流区由于泥沙碰撞切应力的存在，使得扩散理论不能解释此区域的泥沙含量分布规律。
