Scour Genius: Monitoring Scour Effects on Structures

Structural Health Monitoring 2015, 2015
Scour is a phenomenon that occurs all over the world; it is a major cause of bridge failure and the implications of scouring events are large. Affecting the structural integrity of a bridge, the rate and occurrence of scour must be adequately monitored using up-to-date methods and technologies. This monitoring can help prevent a sudden and catastrophic

Scour effects on lateral behavior of pile groups in sands

, 2020
Scour that removes soils around foundations supporting bridges and marine structures is the major cause for structural failures. Recently, many studies have been conducted to investigate scour effects on lateral behavior of single piles using numerical ...

Risk-based methodology for scour analysis at bridge foundations

, 2020
The collapse of bridges inevitably leads to economical losses and may also be responsible for human fatalities. A bridge may fail due to several reasons, with local scouring around its foundation being the most common.

Application of endurance time method to seismic fragility evaluation of highway bridges considering scour effect

, 2020
Earthquake and flood scour are two main causes of failures to highway bridges. This study developed an alternative fragility analysis framework of bridges based on endurance time method (ETM).

Scour and Scour Protection

2019
Scour (the removal or redistribution of erodible material) may occur on the boundaries of unlined channels or adjacent to concrete structures in rivers. Criteria are presented for predicting the likelihood of scour in cohesionless material, and for designing loose protective linings (riprap).

Prediction of current-induced scour depth around pile groups using MARS, CART, and ANN approaches

, 2020
Scour 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.

The local scour around bridge piers—a review of remedial techniques

ISH Journal of Hydraulic Engineering, 2020
The paper briefly describes the mechanics of local scour process around bridge pier and gives an in-depth review of the various techniques employed for local scour control and protection. The most common armoring device is placing of riprap stones around

Jet scour

Proceedings of the Institution of Civil Engineers - Maritime Engineering, 2011
This paper discusses scour without bed protection, such as propeller scour, two-dimensional horizontal, three-dimensional horizontal scour generated by free jets downstream of gates and outlets, two-dimensional vertical and three-dimensional vertical scour.

Scour and scour countermeasures at bridge sites

Transactions of Tianjin University, 2008
This paper examines scour and scour countermeasures at bridge piers and abutments. Abutment scour is by far more complex than its counterpart associated with piers because of the possibility of the presence of a floodplain. Notwithstanding this, the mechanism of scour at both piers and abutments is very similar; moreover, the failure mechanisms ...
