Abstract Weirs are hydraulic obstructions constructed across an open-channel flow causing a rise in water which is useful to convert the channels upstream as well using these structures measuring device. There different types, and sharp-crested weir one of them. Local scour downstream most critical problems affecting their safety stability. Many studies conducted prevent facilities from collaps...

Forced hydraulic jump in a horizontal stilling basin with one and two continuous sills at the downstream end of an ogee standard weir was investigated. Experiments were completed on sills of five different heights which were fixed at two different distances from the toe of the weir. The main characteristics of the jump such as the sequent depth ratio, relative roller &#10length, and relative en...

With the continuous operation of check dams, silting elevation whole dam gradually increases. When height is close to broad-crested weir, it will result in a large change hydraulic characteristics original flow pattern. For subsequent reinforcement work, necessary know how excessive sediment deposition affects overflow from weir into spillway. However, few studies about discharge coefficients a...

Many works have considered two-dimensional free-surface flow over the edge of a plate, forming waterfall, and with uniform horizontal far upstream. The is assumed to be steady irrotational, whilst fluid inviscid incompressible. Gravity also taken into account. In particular, amongst these works, numerical solutions for supercritical flows been computed, utilising conformal mappings as well seri...
