Particle swarm optimization model to predict scour depth around a bridge pier

Shahaboddin SHAMSHIRBAND, Amir MOSAVI, Timon RABCZUK

Frontiers of Structural and Civil Engineering 2020, Volume 14, Issue 4,   Pages 855-866 doi: 10.1007/s11709-020-0619-2

Abstract: Scour depth around bridge piers plays a vital role in the safety and stability of the bridges.The former approaches used in the prediction of scour depth are based on regression models or black boxaims to develop new equations using particle swarm optimization as a metaheuristic approach to predict scourMoreover, sensitivity analysis is conducted to achieve the most effective parameters in the estimation of scourThe derived equations can be used as a suitable proxy to estimate scour depth in both experimental and

Numerical modeling of current-induced scour around multi-wall foundation using large-eddy simulation

Frontiers of Structural and Civil Engineering 2023, Volume 17, Issue 4,   Pages 546-565 doi: 10.1007/s11709-023-0943-4

Abstract: However, research concerning the scour mechanism of multi-wall foundations (MWFs) remains scarce, hinderingfour MWFs with different wall arrangements and inflow angles, including the flow field analysis and scourIt was found that the maximum scour depth of MWFs with an inflow angle of 0° was smaller than that ofMeanwhile, changing the inflow angle significantly affects the scour characteristics of MWFs arranged
