Laboratory Study of Local Scour Around an Array of Pile Groups in Clear-Water Scour Conditions
Journal of Marine Science and EngineeringCurrent-induced local scour around pile groups weakens the capacity of structures. In this paper, experimental tests of local scour around an array of 5 × 5 pile groups were conducted in a steady current in a hydraulic flume.

Log-Vane Scour in Clear Water Condition [PDF]
River Research and Applications, 2014 Log-Vane is a grade-control structure of common use to stabilize river bed and river banks. The purpose of this paper is to study the scour phenomena downstream of Log-Vanes in straight rivers. The main goal is to obtain design equations to determine the main scour parameters and the scour morphology.

Clear-Water Scour at Pile Groups [PDF]
Journal of Hydraulic Engineering, 2013 AbstractGroups of piles are frequently used as bridge foundations. Different group configurations, characterized by different pile spacing, skew-angle, number, and arrangement of pile group columns interact differently with the flow field and lead to different scour patterns and equilibrium scour depth.

Clear-water scour evolution at dual bridge piers [PDF]
Canadian Journal of Civil Engineering, 2017 For the efficient design of bridge pier footings, computation of time-evolution of scour depth around bridge piers is essential. In this paper, a semi-empirical model is developed to estimate the temporal variation of clear-water scour depth at a couple of identical cylindrical uniform piers in tandem arrangement. The experiments are carried out using

Characteristics and mechanism of local scour reduction around spur dike using the collar in clear water. [PDF]
Sci RepTo reduce the local scour around the spur dike, the U-shaped collar is proposed in this study. The influence of the collar's length, width, and porosity on the local scour reduction in clear water is studied by model tests and numerical simulations ...

Experimental investigation and flow analysis of clear-water scour around pier and abutment in proximity [PDF]
Water Science and Engineering, 2022 Local scour around bridge piers and abutments is one of the most important causes of bridge failure. Despite a plethora of studies on scour around individual bridge piers or abutments, few studies focused on the joint impact of a pier and an abutment in ...

Temporal clear-water scour evolution at rock weirs
Shui kexue jinzhan, 2022 Rock weirs are commonly used eco-friendly river training structures. However, water flow over rock weirs can cause local scour, resulting in structural failure.
