试论初生态侵蚀性坡面薄层水流的基本动力特性

Attempt for Expounding Basic Dynamic Characteristics of Very Shallow Flow on Preliminary Eco-erosion Slopes

从水力学与泥沙运动力学观点，对初生态侵蚀性坡面薄层水流的基本动力特性，如流道、流态、临界水深、阻力系数等几个基本问题，作了半理论性探讨。

From the viewpoint of hydraulics and sediment transport mechanics,several prob-lems of the basic dynamic characteristics of the very shallow flow on the preliminary eco-erosionslopes such as the flow path,flow pattern,critical depth,the coefficient of drag and others havebeen semi-theoretically studied.
