Swash zone hydrodynamics has significant coastal geomorphological and engineering implications. However, there is still a research gap in fully understanding the response of bore-driven swash to varying beach slopes. Therefore, this study, laboratory experiments were performed flume investigate flows over impermeable smooth beaches with mild slope (1:35), steep (1:10), composite (1:35–1:10), re...

Abstract Bridge pier is a common feature in hydraulic structure. Its impact to the river usually occurs group form rather than single pier, so this challenging piers-group influence towards hydraulics and turbulence needs be explored. In paper, measurements were conducted using an Acoustic doppler velocimeter (ADV) study velocities three dimensions (longitudinal, transversal, vertical). Based o...

The many hydrodynamic implications associated with the geomorphological evolution of braided rivers are still not profoundly examined in both experimental and numerical analyses, due to generation three-dimensional turbulence structures around sediment bars. In this research, 3D velocity fields were measured through an acoustic Doppler velocimeter during flume-scale laboratory runs over emergin...

Abstract This research aims to investigate the near-bed turbulent flow characteristics in a meandering channel with both mobile bed and immobile conditions. Experiments were performed prismatic rectangular non-uniform sand of size d50 = 0.523mm. The three-dimensional instantaneous fluid velocity was collected using Acoustic Doppler velocimeter which will provide important results related turbul...
