坡流类型及坡地水力侵蚀计算方法

Types of Hillside Flow and Calculation Method of Hillside Scouring

从紊流力学与山坡水文学观点出发，研究了坡面流类型、坡地冲刷与坡形演变的力学机制，提出了关于坡地动力学的一些基本原理和计算坡地冲刷的实用方法。从而可从成因上估算裸露地表或植被条件下的冲刷强度，为水土保持工程设计、流域综合治理规划提供理论依据。

The types of hillside flow , the scouring m echanism and evolution of the profileform are studied on the basis of turbulent m echanics and hillside hydrology theory. Som ebasic concepts ofhillside dynam ics and theoreticalcalculation m ethod ofhillside scouring areput forw ard. By the m ethod, the scouring intensity can be estim ated fornaked or vegetation covered surface from the form ation causes. The w orks also provide a scientific base fordesigns ofsoiland w ater conservation projects and com prehensive controlplan.
