Reduction of scouring depth by using inclined piers

Canadian Journal of Civil Engineering, 2010
The aim of this experimental study is to examine the effect of inclination of dual bridge piers on scour depth under clear-water conditions for various uniform flow depths. Duration of 4 h was used in the experiments for each run. Scour depths were measured at four different points around the piers. The depths of local scour around inclined piers were

Towards a simple calibration of a scour-depth sensor

2022
This extended abstract presents an innovative method for scour monitoring, based on the dynamic response of a bridgepile embedded in the riverbed. Apart from the mechanical and physical characteristics of the pile itself, soil-structure interaction (SSI)affects the dynamical behaviour of the system.

Scour‐depth Prediction Under Armoring Conditions

Journal of Hydraulic Engineering, 1989
A 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

Modelling the scour depth near the bridge pier

Вычислительные технологии
Представлено численное моделирование местного размыва грунта возле мостовой опоры, вызванного речным потоком. Использованы трехмерная гидродинамическая модель с параметризацией турбулентного обмена и модель переноса осадков. В результате моделирования установлено, что воронка размыва стабилизируется.

Efficacy of Marine Electrical Resistivity Surveys to Determine Maximum Scour Depth and Scour Infill

Transportation Research Record: Journal of the Transportation Research Board
The maximum depth of bridge scour typically occurs during peak flood conditions when it is too dangerous to collect measurements. Often, the maximum depth is obscured by additional redeposited sediment. Applied geophysical methods are commonly used to detect the depth of scour infill and estimate maximum scour depth.
