Abstract: A calculation procedure for the analysis of flow near a change in a slope from mild to steep in a wide rectangular channel is presented and evaluated. It is assumed that the viscous effects are negligible and that flow is ...

Abstract: A numerical method of solution of the inviscid flow under planar gates is developed and evaluated. The results of the calculations show good agreement with previous inviscid flow solutions and with experimental results for ...

Abstract: The most common types of weirs are the broad-crested weir, the sharp-crested weir, the circular-crested weir, and nowadays, the ogee crest weir. Advantages of the cylindrical weir shape include the stable overflow pattern, ...

Abstract: In open channels, the transition from supercritical to subcritical flows is called a hydraulic jump. For low upstream Froude numbers, free-surface undulations develop downstream of the jump and the hydraulic jump is called ...

Abstract: The writers measured velocity, pressure and energy distributions, wavelengths, and wave amplitudes along undular jumps in a smooth rectangular channel 0.25 m wide. In each case the upstream flow was a fully developed shear ...
