摘      要：Based on the continuity equation, the distribution of vertical velocity in equilibrium steady non-uniform and unsteady open-channel flows were deduced theoretically. Then a recently developed Acoustic Doppler Velocity Profiler (ADVP) at the Swiss Federal Institute of Technology was used to measure instantaneously the flow profiles. From these measurements, the vertical velocity and the other flow parameters were obtained. Additional data measured using an Acoustic Doppler Velocimeter (ADV) at the Nanyang Technological University were also presented. The agreement between the theoretical distribution of vertical velocity and the measured data is reasonably good.
