Summary
This paper is concerned with longitudinal and transverse variations of the sear stress on the wetted perimeter of a sloped rectangular open channel in a hydraulic jump. It is found that the locus of the maximum bed shear stress upstream and downstream of the hydraulic jump indicates a clear meandering tendency. That is, the meandering locus of the maximum bed shear stress appears whether the flow is supercritical or subcritical. In the jump region, the locus almost follows the central axis of the channel, and the amplitude and wave-length are very small. However, downstream of the jump region the locus of the maximum bed shear stress starts meandering, and the amplitude and wave-length vary in an irregular manner.
