Ice scour is the most disruptive and widespread physical disturbance that naturally affects the coastal benthos in polar waters, where it creates a mosaic of disturbances in various stages of recolonization. The purpose of this study was to (1) determine the timing and sequence of biotic recovery following ice scour disturbance of soft sediment and (2) test the general hypothesis that ice scour...

An assessment of maximum scour depth downstream of grade control structure is essential for its proper planning, design and management. Most of the scour depth prediction formulae available in the literature have been developed based on the analysis of the laboratory/field data using the statistical method such as the regression method (RM). The alternative recent approaches such as artificial ...

The scour modelling in cohesive beds is relatively more complex than that in sandy beds and thus there is limited number of studies available on local scour at bridge abutments on cohesive sediment. Recently, a good progress has been made in the development of data-driven techniques based on artificial intelligence (AI). It has been reported that AI-based inductive modelling techniques are freq...

Scour around non-circular cylinders has seldom been studied before. This paper aims to numerically investigate the flow behaviour and evolution of local scour two single square-shaped piers with 90 ° (square pier) 45 (diamond orientation angles under steady-current live-bed conditions. For this purpose, a coupled approach between hydrodynamic morphodynamic model is developed validated against e...

Rapid expansions of the offshore wind industry have stimulated a renewed interest in behavior turbines. Monopile, tripod, and jack-up turbines support most These foundations are sensitive to scour, reducing their ultimate capacity altering dynamic response. However, existing approaches ignore seabed’s rheological properties scour process. This study focuses on development around turbine foundat...

River bridge piers may collapse due to the local scour around their foundations. It is known that an effect of three-dimensional flow field develops near pier and geometric complexity a non-cylindrical may, correspondingly, increase process. also various devices be used as countermeasures. This manuscript explores use bed sill countermeasure for at complex compound array piles, pile cap, two in...

When depth of flow past a river bridge exceeds opening under the bridge, the flow under the bridge becomes pressurized. The water is directed downward and under the bridge deck, causing increase in velocity and shear stress on the bed thereby increasing bed scour. This is termed as Pressure Flow Scour. The present study investigates the phenomenon of pressure flow scour resulting from a submerg...
