引言 1.对于两平行平面墙间的平面水跃已进行过很多的研究。然而,在广泛的水利工程范畴内,水跃也可以是非平面的,例如,当拦河坝开启单扇闸门时或在渠道突然扩大的地方。对于这类情况,水流资料有限,而用于估算水深的一些经验公式之间也存有极大的差异。2.本文描述一个窄明渠急流与一个宽明渠缓流交汇处,水跃形成的实验室模型研 INTRODUCTION 1. A great deal of research has been carried out on the plane water jump between two parallel plane walls. However, in the context of a wide range of hydraulic engineering, hydraulic jumps can also be non-planar, for example, when a barrage opens a single-headed gate or where a sudden expansion of a channel occurs. For such cases, water flow data are limited, and there are significant differences between some empirical formulas used to estimate water depth. 2. This paper describes a laboratory model of water jets formed by a narrow open channel rapids and a wide open channel slow flow interchange
