Estimation of Maximum Scour Depth and Scour Pattern Around Submerged Spur-Dike [PDF]
, 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.

A Comprehensive Method of Calculating Maximum Bridge Scour Depth [PDF]
Water, 2018 Recently, the issues of scour around a bridge have become prominent because of the recurrent occurrence of extreme weather events. Thus, a bridge must be designed with the appropriate protection measures to prevent failure due to scour for the high flows to which it may be subjected during such extreme weather events.

Maximum scour depth at piers in armor-beds [PDF]
KSCE Journal of Civil Engineering, 2009 The paper presents a design method to determine the maximum equilibrium scour depth at piers embedded in a sand-bed overlain by a thin armor-layer of gravels using the experimental data of Dey and Raikar and those of Ettema. The proposed equation is in terms of empirical relationships, termed K-factors, which account for the effects of flow depth, pier

FLOW-3D MODELLING OF THE DEBRIS EFFECT ON MAXIMUM SCOUR HOLE DEPTH AT BRIDGE PIERS [PDF]
38th IAHR World Congress - "Water: Connecting the World", 2019 Bridge foundations are frequently inserted in riverbeds constituted by alluvial material, being, therefore, subjected to scouring processes. Such phenomenon is aggravated during flood events due to the increase of water flow or due to the increase of the debris carried by the flow that can pile up along the bridge structural elements.

Study on Maximum Scouring Depth of Gravel Channels [PDF]
Procedia Engineering, 2012 AbstractThe local scour depth is a key parameter in the design of levee engineering. Based on experiment data, a non-dimensional analysis for the prediction of local scour depth is related to the approach flow velocity, flow depth, flow angle, scope of levee and the particle size of the bed sediment.

Influence of scour depth and flow velocity field on large-diameter pier group pile foundations [PDF]
Frontiers in Marine ScienceSea-crossing bridges face critical challenges due to scour, which can destabilize foundations. This study investigates the scour characteristics of the large-diameter main pier of the Haiwen Bridge, with a pile diameter of 4.3 meters. Seabed changes were

Application of Euler- Euler method in estimation of maximum depth of local scour [PDF]
مجله مدل سازی در مهندسی, 2017 Local scour of hydraulic structures has a great influence on the design of these structures. Therefore, investigation of the flow and bed profile changes, affected by the presence of different structures is inevitable. In this paper, a three-dimensional Eulerian-Eulerian model is used to estimate the maximum scour depth downstream of hydraulic ...

Prediction of Maximum Scour Depth Using Scaled Down Bridge Model in a Laboratory [PDF]
, 2019 Recently, United States faced catastrophic flooding in West Virginia, Texas, Louisiana, Oklahoma, Arkansas, and the flooding resulted in several bridge failures. Among them, bridge scour is one of the main causes behind many bridge failures and financial losses as well as loss of life.

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.
