Abstract: The objective of this research is to study the relationship between the coherent flow structures and the hydrodynamic forces leading to entrainment of a spherical bed sediment particle for a rough bed uniform turbulent ...

Abstract: When estimating design local scour depths at structures where the design flows have short durations, equilibrium scour depths can be too conservative. Attempts to develop methods to accurately estimate scour rates and times ...

Abstract: An experimental study of flow-induced failure of cable-tied blocks is presented. The particular failure mechanism studied is overturning and rolling up of the leading edge of a cable-tied block mat. Individual blocks were ...

Abstract: An experimental study of scour countermeasures for spill-through abutments situated on the flood plain of a compound channel is reported. The purpose of the study was to determine the variations in the scour hole geometry ...

Abstract: The partial duration series (PDS) model is preferable for hydrological frequency analysis when dealing with values exceeding a certain threshold, and the model is capable of capturing more information about extreme events ...

Abstract: An experimental study of scour countermeasures for wing-wall abutments under mobile-bed conditions is reported. The purpose of the study was to determine the required apron size to protect a wing-wall abutment from scour ...

Abstract: Pressure sewer networks offer a flexible alternative to more traditional gravity-based systems for the conveyance of wastewater. Some of the issues associated with pressure sewer networks (e.g., odor, septicity) arise ...

Abstract: Laboratory experiments of sediment entrainment were carried out in a flume for different flow configurations with particle image velocimetry (PIV) used to measure the flow velocity. The experiments were done in a low ...
