坡面流是研究土壤侵蚀机理的关键,流速计算受多因素影响尤显复杂,为此提出了应用陡坡紊流边界层名义厚度方程求解坡面流流速的分布,探讨了经典边界层理论模型,修正了传统边界层的势流流速,推导出适用于描述坡面流流动特性的理论模型,考虑到下垫面及水温等的影响,构建了分类计算平均流速的计算模型,并验证了计算模型的可行性。
The slope flow is the key to study the mechanism of soil erosion. The calculation of flow velocity is complicated by many factors. Therefore, the distribution of slope flow velocity is proposed by using the nominal thickness equation of the steep slope turbulent boundary layer. The theoretical model of the boundary layer, The flow velocity of potential flow in the traditional boundary layer was corrected, and a theoretical model suitable for describing the flow characteristics of slope flow was deduced. Considering the influence of underlying surface and water temperature, a computational model for calculating the average flow velocity was established, and the calculation model Feasibility.
