Nonlinear weirs are regarded as important hydraulic structures for water level adjustment and flow control in channels, rivers and dam reservoirs. One example of non-linear weirs is shaped as curved-zigzag. The crest axis of these weirs is non-linear. At a given width, the crest length is greater than that of the conventional linear weirs. Thus, they achieve a higher flow rate for an identical ...
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...
