Experimental study on local scour depth around pile groups
Energy Reports, 2022 An accurate prediction of local scour depth at piles is essential for bridge safety. In order to obtain the prediction formula of local scour around pile groups, a series of local scour experiments of pile groups were carried out.

Interaction of Bridge Pier and Abutment on Local Scour Around Them [PDF]
علوم و مهندسی آبیاری, 2016 The local scour around bridge pier and abutment in recent years has been widely studied by different authors. Scant information exists as to how bridge pier proximity to abutment affects scour depth at an abutment and at a pier. Due to the fact that many

Mean Flow Structure and Local Scour around Single and Two-Column Bridge Piers [PDF]
علوم و مهندسی آبیاری, 2019 Bridges constructed across rivers are among the most important structures, especially during and after flood events. Bridge piers are exposed to some hazardous factors such as local and contraction scour hydrodynamics.

Scour depth model for grade-control structures [PDF]
Journal of Hydroinformatics, 2017 Abstract Grade-control structures (GCS) are commonly used to protect fish habitat by preventing excessive river-bed degradation in mountain streams. However, flow over the GCS can cause localized scour immediately downstream of the weir. This paper aims to develop more accurate models for prediction of the maximum scour depth downstream ...

Estimation of Maximum Scour Depth and Scour Pattern Around Submerged Spur-Dike
, 2022 Scouring due to turbulent flows is a process that naturally happens around river structures, including river training or riverbank protection works such as spur dikes, submerged vanes, etc. present experimental study aims to estimate the maximum scour depth around submerged spur dikes, which have not been studied as extensively.

Large-scale experimental study on scour around offshore wind monopiles under irregular waves
Water Science and Engineering, 2022 The Keulegan-Carpenter (KC) number is the main dimensionless parameter that affects the local scour of offshore wind power monopile foundations. This study conducted large-scale (1:13) physical model tests to study the local scour shape, equilibrium ...

Evolution of local scour around a collared monopile through tidal cycles [PDF]
, 2012 This paper presents the results of an experiment designed to assess the time-development of scour around an offshore wind turbine collared monopile over a number of tidal cycles. One collar shape and location was investigated.

Maximum Abutment Scour Depth in Cohesive Soils [PDF]
Scour and Erosion, 2010 Most conventional methods to predict the depth of abutment scour were developed with flume test results using cohesionless soils, and those methods have been used to the abutment scour depth prediction in cohesive soils. Generally floodplains where most abutments are located are composed of less erodible soils such as cohesive soils.

Validation of some bridge pier scour formulae using field and laboratory data [PDF]
, 2005 Estimation of maximum local scour depth at the bride pier site is necessary for the safety and economy of the designed bridge. Numerous formulae are available and almost all of these formulae were developed based on laboratory data.
