Abstract: This study explores the formation of bed features in nonuniform sediments. Experiments conducted in a recirculating flume show that the amount of sediments on the bed surface influence the size of the bed features in ...

Abstract: This paper investigates the effect of spoiler orientations on wave‐induced scour around a submarine pipeline. Experiments conducted under pure wave action show that the spoiler can increase both the scour beneath (tunnel ...

Abstract: Measurements of the mean and turbulence characteristics in nonuniform open-channel flows were carried out using a 3D acoustic Doppler velocimeter. Both accelerating and decelerating flows were investigated. Analyses based ...

Abstract: An alternative approach to recording and analyzing point rainfall is proposed. This alternative measure makes use of simple modifications of an autographic rain gage and a dedicated controller to monitor pulses generated ...

Abstract: This paper describes the effect of bed surface structure on the rolling stability of a cohesionless spherical particle. The bed surface structure was investigated in terms of the vertical and horizontal orientation. The ...

Abstract: The effect of bed-load movement on the friction factor of pipe flow and open-channel flow was studied experimentally. The measured results for flows without bed-load movement for both of these flows compares well with the ...

Abstract: This study investigates the mechanism and the characteristic parameters affecting local scour around a vertical pile caused by turbulent circular wall jets. There are two basic scouring mechanisms: the pile obstruction and ...
