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.

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

Riprap mitigation of downstream scour at grade-control structures considering tailwater depth and layer thickness [PDF]

Scientific Reports
Downstream scour at grade-control structures (GCSs) poses a serious threat to structural stability and riverbed integrity. Among various countermeasures, riprap has long been recognized as a cost-effective and readily available solution for scour ...

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.

Estimation and interpretation of equilibrium scour depth around circular bridge piers by using optimized XGBoost and SHAP

Engineering Applications of Computational Fluid Mechanics, 2023
Most bridge failures result from scouring around bridge piers, resulting in economic losses and risks to public safety. The conventional equations for predicting the depth of scour at bridge piers have several limitations: (1) They mainly use regression ...

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.
