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 ...

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.

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.

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

Estimation of Maximum Scour Depth and Scour Pattern Around Submerged Spur-Dike
, 2023 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.

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 ...

Journal of the Civil Engineering Forum, 2016 River bed control structure what so called groundsill or bottom sill is built for controlling a river bed to remain stable against degradation. Unlike other river obstacles, the presence of groundsill might cause sediment retention upstream of the structure; hence it reduces the supply of sediment to the downstream part of the river.

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 ...
