Abstract: Unimpeded waterway connectivity is a requirement for all freshwater fish. While box culverts are considered the most effective design in terms of upstream fish passage, circular culverts are very common. Detailed hydrodynamic ...

Abstract: A spillway is a conveyance structure designed to pass flood waters. The construction of steps down the steep chute may contribute to some energy dissipation, in turn reducing the size of the downstream energy dissipator. ...

Abstract: Culverts are among the most common hydraulic structures. Modern designs do not differ from ancient structures and are often characterized by significant afflux at the design flows. A significant advance was the development ...

Abstract: The present study examines the free-surface properties of undular tidal bores observed for
