摘要：

Undular hydraulic jumps in sloping rectangular channels have been experimentally investigated. The upper limit of the inflow Froude number for the formation of an undular jump depends on the channel slope; if the channel slope is steeper than the critical slope. The streamwise changes of the surface profile, the bed pressure head, and the bed velocity in undular jumps have been characterized by the channel slope. The effects of channel slope on the wave height, the wave length, and the amplitude of undular jumps have been shown. Also, surface profiles of undular jumps have been compared with theoretical results proposed by Grillhofer and Schneider. The applicability of the theoretical results is discussed.
