Scour‐depth Prediction Under Armoring Conditions
Journal of Hydraulic Engineering, 1989A simple procedure is proposed to predict scour depth on an alluvial bed having graded materials under certain flow conditions that can produce an armor layer at the bed surface. The procedure is based on calculation of an active or mixing layer that supplies the fine particles to the sediment load transported by the flow and from where all the heavier

Prediction of current-induced scour depth around pile groups using MARS, CART, and ANN approaches
, 2020Scour around piles is considered as one of the most important phenomena which could undermine the stability of piles. Data-driven methods are now being used more and more to predict complex phenomena such as scour around of pile groups.

Experimental Analysis of the Scour Pattern Modeling of Scour Depth Around Bridge Piers
Arabian Journal for Science and Engineering, 2017Bridge pier scouring measurement in the field, especially during flood season, is very difficult. This study experimentally investigated the pier scour pattern to find better alternatives to represent the actual field conditions. For this purpose, piers of different shapes (circular and square) and different sizes were modeled in the laboratory.

Limits on Coastal Scour Depths due to Tsunami
International Efforts in Lifeline Earthquake Engineering, 2013Tsunami scour has received increasing attention over the past decade, given its role as a critical failure mode for building damage and, in particular, the wide scale damage to infrastructure resulting from the 2004 Sumatra Andaman Tsunami and the 2011 Tohoku Tsunami.

Evolution of Scour Depth at Circular Bridge Piers
Journal of Hydraulic Engineering, 2004Experiments of bridge pier scour are carried out under steady and unsteady clear-water scour conditions with uniform and nonuniform sediments. Around the pier nose, the sediment size variation of surface bed materials is investigated, and a regressed formula is obtained for estimating the mixing layer thickness in terms of median sediment size and ...

Particle swarm optimization model to predict scour depth around a bridge pier
Frontiers of Structural and Civil Engineering, 2019Scour 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 box models in which the first one lacks enough accuracy ...

Estimation of scour depth around submerged weirs using self-adaptive extreme learning machine
Journal of Hydroinformatics, 2019In this study, the equilibrium scour depth downstream of the weir (ds-a), the maximum scour depth downstream of the weir (ds-max), the equilibrium scour depth upstream of the weir (dus-a) and the maximum scour depth upstream of the weir (dus-max) were ...
