Abstract: Hydraulic jumps on the steps of a stepped spillway were investigated analytically, physically, and numerically. Using classic hydraulic formulae, a conceptual prototype was designed. A large scale model was adapted and an ...

Abstract: Manhole drops in drainage systems are often designed for providing energy dissipation, for controlling high velocities and for minimizing sewers structural damage. The flow is characterized by excessive air-entrainment and ...

Abstract: This paper deals with the numerical investigation of the drainage efficiency of a continuous transverse gully with the grate’s slots aligned in the flow direction and compared with experimental data sets. The gully efficiency ...
