Abstract: This note focuses on the temporal and spatial evolution of local scour below low-head spillways. Steady-flow experiments were carried out in a 1-m wide and 20-m long rectangular straight channel. The jet was generated by ...

Abstract: Storm overflow structures in combined sewers are used to separate sewage from storm water. For subcritical approach flow, sideweirs are currently used; however, they often behave hydraulically poor. This study was conducted ...

Abstract: Seismic isolation is a widely adopted technology for the protection of building infrastructure from earthquakes. As one of the most effective seismic protection devices, curved surface slider (CSS) systems have been studied ...

Abstract: Two related problems of sediment hydraulics are addressed: (1) Inception of sediment transport for nearly uniform flow of both uniform and nonuniform sediment beds for two different sediment densities and grain sizes ranging ...

Abstract: Scour related to bridge hydraulics received much attention in the past decade, including its relation to flood hydrology and hydraulic processes in addition to steady flow. This paper presents new research on bridge pier ...

Abstract: This research intends to clarify the limitations of a local scour equation recently proposed, based on extended laboratory data collected at VAW, Zurich, Switzerland. The present project is concerned with four items: (1) ...

Abstract: This research intends to provide new insights on sediment transport at bridges, exploring the features of migrating dune-like bed forms generated immediately behind piers or abutments by local scour processes. An extended ...

Abstract: The Sector Venturi is a novel design to determine discharge in sewers. Its main features are simplicity, accuracy of ±5%, and low cost. Further, the modular limit is comparable to standard flumes, and the capacity is equal ...
