Scour protection around bridge pier and two-piers-in-tandem arrangement
ISH Journal of Hydraulic Engineering, 2021In the present study, experiments were carried out on circular model bridge piers individually as well as with two-piers-in-tandem arrangement under clear water scour conditions predominantly caused by formation of horseshoe vortex.

Scour around non-circular cylinders has seldom been studied before. This paper aims to numerically investigate the flow behaviour and evolution of local scour around two single square-shaped piers with 90 ° (square pier) and 45 ° (diamond pier ...

Dynamic impedance of monopiles for offshore wind turbines considering scour-hole dimensions
, 2021This study presents an effective solution to evaluate the dynamic impedances of scoured monopiles for offshore wind turbines in a wide excitation frequency range, which can properly account for both the effects of the scour-hole dimensions as well as of ...

Reduction of time-dependent scour around piers using collars
, 2020In the present study, the effect of collar on temporal scour depth variation at the base of a collar-protected circular pier was investigated. Experimental results revealed that a collar performs efficiently by reducing the rate of temporal scour depth ...

Characterization of horseshoe vortex in a developing scour hole at a cylindrical bridge pier
International Journal of Sediment Research, 2019Since local scour at bridge piers in rivers and estuaries is a major cause of bridge failure, estimation of the maximum local scour depth is of great importance to hydraulic and coastal engineers.

Experimental study on local scour at complex bridge pier under combined waves and current
, 2020This paper presents an experimental study on scour at complex bridge piers exposed to combined waves and current. Regular waves were produced with various strength and superimposed on co-directional current with constant velocity.

Reduction of local scour around a bridge pier by using different shapes of pier slots and collars
, 2020Local scour around bridge piers is one of the main causes of bridge failure all over the world. Experimental and hydraulic models were carried out to investigate two types of scour reduction methods around a single cylindrical pier, namely the pier’s ...
