Prediction of maximum scour depth at clear water conditions: Multivariate and robust comparative analysis between empirical equations and machine learning approaches using extensive reference metadata.

Journal of Environmental Management
Flow obstructed by bridge piers can increase sediment transport leading to local scour. This local scour poses a risk to the stability of bridge structures, which could lead to structural failures.

Maximum Clear-Water Scour Around Circular Piers

Journal of the Hydraulics Division, 1981
The potential predictors of the maximum clear-water scour are compared with the available experimental data. The range of flow parameters, for which these formulas either overpredicted or underpredicted, are delineated. Comparison indicates that the scour formula by Laurson and Toch is the best predictor among those examined, for it encompasses all ...

Armor-Limited Clear-Water Contraction Scour at Bridges

Journal of Hydraulic Engineering, 1995
A simplified model of streambed armoring is used to extend Laursen's well-known equation to include the limiting effects of a coarse surface layer when calculating clear-water contraction scour at bridges. An empirical relation for selective entrainment of gravel from naturally sorted riverbed material is used to estimate the smallest nontransportable ...
