Numerical investigation of local scour and turbulence characteristics around circular bridge piers in straight channel

Key Points

• The aim is to investigate the effects of local scour and turbulence around circular bridge piers in a straight channel using numerical methods.
• Used numerical modeling to simulate flow around circular bridge piers.
• Analyzed local scour depth and turbulence characteristics in a straight channel.
• Studied hydrodynamic forces affecting scour development.
• Identified significant local scour around circular piers under various flow conditions.
• Found that turbulence profiles vary considerably at different heights above the bed.
• Quantified the relationship between flow speed and scour depth.
