A tidal bore is a positive surge taking place during the flood tide with a large tidal range and the bore corresponds to the leading edge of the tidal wave propagating upstream. In this study, some physical modelling was performed to investigate[...]

A simple model for predicting the vertical distribution of wave-induced horizontal orbital velocities inside submerged porous structures is presented. A velocity profile is formulated based on the exponential profile of the nonlinear wave theory[...]

Experiments involving both a circular wall jet and an impinging jet were conducted, as occurring at irrigation control structures or at dams with combined crest and low-level spillways. The effects of the non-dimensional parameters on the scour [...]

Piano Key Weirs (PKWs) are an alternative to linear overflow structures, increasing the unit discharge for similar heads and spillway widths. Thus, they allow to operate reservoirs with elevated supply levels, thereby providing additional storag[...]

Traditional characterization of the leak head–discharge relationship in pipeline systems relies on the use of power law functions to explain the increase in leakage rate with pressure when network and laboratory data are analysed. However, recen[...]

Stepped chutes effectively dissipate the energy of supercritical flow of steep channels. In general, stepped chute flows are characterized by self-aeration. For their hydraulic design, it is important to know the aerated flow depth, the aerated [...]
