TLDR
In this paper, the results of laboratory experiments on the clear-water local scour of cohesionless bed sediment at cylindrical piers are presented, where the equilibrium depth of local sink is related to the particle size distribution of the bed sediment, relative to the pier diameter, flow depth, and the mean particle size of the sediment.Abstract:
The results of laboratory experiments on the clear-water local scour of cohesionless bed sediment at cylindrical piers are presented. Based on the data, equilibrium depth of local scour is related to the particle size distribution of the bed sediment, mean particle size of the bed sediment, relative to the pier diameter, flow depth relative to both the pier diameter and the mean particle size of the bed sediment. A formula for estimating the maximum depth of local scour is also given.read more

Numerical and experimental investigation of flow and scour around a circular pile
TL;DR: In this article, a three-dimensional model of a vertical circular pile exposed to a steady current is studied numerically and experimentally, which is applicable to cases where the Froude number is small (Fr < 0(0.2)).

Scale Effect in Pier-Scour Experiments
TL;DR: In this paper, the effects of pier width on local scour depth were investigated and it was shown that scour depths do not scale linearly with pier width unless there is more-or-less complete geometric similitude of pier, flow, and loose-bed particles.

Experimental Investigation of Clear-Water Local Scour at Pile Groups
TL;DR: In this paper, a variety of conditions including different pile group arrangements, spacing, flow rates, and sediment grain sizes are considered to predict the maximum local scour depth for the pile groups.

Functional Trends of Scour at Bridge Piers
TL;DR: In this paper, the functional trends of the local scour depth at a bridge pier in subcritical flow are discussed and related to flow and sediment parameters leading to a framework within which the scour depths under given conditions can be estimated.

Scour around Pile in Combined Waves and Current
B. Mutlu Sumer,Jørgen Fredsøe +1 more
TL;DR: In this paper, the results of an experimental study on scour around a pile subject to combined waves and current were presented, where irregular waves were used in the experiments, which were carried out both for normal and irregular waves.

Local Scour Around Cylindrical Piers
TL;DR: In this paper, a review of literature on model and field data is presented, and the empirical data are compared with theoretical considerations, together with a set of design suggestions together with possibilities for protection against scour.

Effect of Sediment Gradation on Clear Water Scour
Arved J. Raudkivi,Robert Ettema +1 more
TL;DR: In this paper, a comparison of the published experimental data on scour depths at bridge piers shows that a large range of values at what appears to be identical conditions can arise from different grain size distributions of the bed material used.
