摘要: |
河床组成、河道比降一定时,合适的入流角能直接产生环流,在此作用下,有纵、横向的泥沙运动,因此,入流角对曲流的形成有着显著的影响。同时,入流角对曲流形成影响的程度取决于河床组成、河道比降等因素。 |

Abstract: |
A suitable inflow angle can directly produce a circulating current for a reach with a certain river bed composition and river gradient. Longitudinal and transverse sediment movement can occur under the action of circulating current, and therefore the inflow angle has remarkable influences on the development of meander. The influence degree depends on the river bed composition, river gradient and other factors. |
Key words: inflow angle,meander,river,model test |
