Hybrid Scour Depth Prediction Equations for Reliable Design of Bridge Piers [PDF]
, 2021 Numerous models have been proposed in the past to predict the maximum scour depth around bridge piers. These studies have all focused on the different parameters that could affect the maximum scour depth and the model accuracy. One of the main parameters

Evolution of local scour downstream of Type A PK weir in non-cohesive sediments
Journal of Hydrology and Hydromechanics, 2022 A large-scale piano key weir laboratory study was conducted to investigate the evolution of the scour process occurring in the downstream basin for two non-cohesive granular bed materials, including the analysis of scour-hole geometry and patterns at ...

Mechanical plaque removal in step‐1 of care
Periodontology 2000, EarlyView., 2023 Abstract Maintaining a regular oral hygiene routine is essential for taking care of our mouths, ensuring healthy teeth, and achieving fresh breath. Patient education on oral hygiene is an important component of their overall treatment. Firstly, patients should be informed about the direct connection between bacteria in dental plaque and oral diseases ...

Effect of trapezoidal collars as a scour countermeasure around wing-wall abutments
Water Science and Engineering, 2018 Local scour around bridge abutments is a widespread problem that can result in structural failure. Collars can be used as a countermeasure to reduce the scour depth.

Generalised maximum scour depth prediction on 2D jet scour and 3D jet scour [PDF]
, 2020 Local scour caused by water jets has been extensively investigated in the past. As the understanding on the jet scour processes improved the study area has transformed from the basic understanding on the 2D jet scour to the formulation on the scour ...

Experimental study on the influence of bed protections on scour depth and scour development in front of sloped embankments [PDF]
, 2020 On the seabed in front of coastal structures sediment movement takes place due to incoming waves. The erosion of sediments creates a scour hole at the toe of structures such as embankments, breakwaters and dikes. This scour hole may lead to instabilities

Local Scour of Bridge Pier Sited on a Multi-Layered Sedimentary Bed in Rivers [PDF]
E3S Web of Conferences, 2020 The riverbeds or sea beds are usually composed of multi-layers of sediments. The scour around bridge piers sited on such beds is vital to the bridge safety, but is still very difficult to be predicated as its complicated interaction between the flow and ...

Experimental study on scour around beveled submerged vanes
International Journal of Sediment ResearchSubmerged vanes are an effective approach to sediment management in river systems. Nowadays, submerged vanes are increasingly utilized in contemporary river engineering due to their convenient and cost-effective installation, which distinguishes them ...

Scour depth model for grade-control structures [PDF]
, 2017 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.
