Prediction of Bridge Pier Scour Depth and Field Scour Depth Monitoring [PDF]

E3S Web of Conferences, 2018
In practice, it is a major challenge in real-time simulation and prediction of bridge pier scour depth, especially using 3-D numerical model. The simulation time spend too much to use 3-D numerical model simulation and inefficiently to predict bridge ...

Equilibrium Scour-Depth Prediction around Cylindrical Structures [PDF]

Journal of Waterway, Port, Coastal, and Ocean Engineering, 2017
Offshore gravity base foundations (GBFs) are often designed with complex geometries. Such structures interact with local hydrodynamics, creating an adverse pressure gradient that is responsible for flow and scour phenomena, including the bed shear stress

Scour Characteristics and Equilibrium Scour Depth Prediction around a Submarine Piggyback Pipeline [PDF]

Journal of Marine Science and Engineering, 2022
Local scour around a submarine piggyback pipeline in combined waves and current is investigated experimentally. Based on the experimental results, the scour evolution and scour morphology are firstly analyzed. Then, a comparison with the equilibrium scour depth Seq between the present experimental data and predicted results is conducted.

Experimental Study on Aspect Ratio and Velocity Intensity of Scour Around Submerged Pile Groups

Frontiers in Marine Science, 2022
Submerged pile groups are important components of complex piers in hydraulic engineering and are analogs for a range of subsea structures. These may sustain severe damages from local scour.

Morphology Evolution of Three-Dimensional Scours Under Submerged Jets

Frontiers in Earth Science, 2022
Through physical model tests, the three-dimensional morphological features and their scale changes with time were measured and comparatively analyzed during the scouring of a homogeneous granular bed surface using submerged oblique jets.

Application of gradient tree boosting regressor for the prediction of scour depth around bridge piers

Journal of Hydroinformatics, 2021
Scour around bridge piers is a complex phenomenon and it is essential to assess or predict the scour hazard around bridge piers in tandem with completely understanding its mechanism.

ANFIS- and GEP-based model for prediction of scour depth around bridge pier in clear-water scouring and live-bed scouring conditions

Journal of Hydroinformatics, 2023
Scour depth prediction is an important aspect of designing a bridge pier structure in a river. Proper modeling of scour depth ensures the sustainability of the structure.

Local scour around a bridge pier under ice-jammed flow condition – an experimental study

Journal of Hydrology and Hydromechanics, 2021
The appearance of an ice jam in a river crucially distorts local hydrodynamic conditions including water level, flow velocity, riverbed form and local scour processes.

Scour depth downstream sharp-crested weir

Journal of Engineering and Applied Science, 2023
AbstractWeirs are hydraulic obstructions constructed across an open-channel flow causing a rise in water which is useful to convert water to the channels upstream as well as using these structures as a measuring device. There are different types, and a sharp-crested weir is one of them.

Length Parameter for Scaling Abutment Scour Depth [PDF]

Water, 2020
Flow constriction caused by bridge abutment increases bed shear stress and thus enhances local scour. For scaling the maximum scour depth at the abutment, either abutment length or flow depth has been empirically used in previous studies. By performing a step-by-step analysis, this study proposes a new length scale, which is able to represent combined ...
