Numerical Modeling of Local Scour in the Vicinity of Bridge Abutments When Covered with Ice
Water, 2023 The occurrence of bridge collapse is frequently attributed to the prevalent erosion in the vicinity of bridge abutments. Accurate determination of the maximum scour depth in the vicinity of bridge abutments is imperative to ensure a secure and reliable ...

Scour Development Around an Oblong Bridge Pier: A Numerical and Experimental Study
Water, 2023 The complex flow structure around bridge piers is challenging for both experimental and numerical studies. Therefore, investigating the capabilities of Computational Fluid Dynamics (CFD) tools in resolving the flow structure and the mechanism of sediment

Validation of some bridge pier scour formulae using field and laboratory data [PDF]
, 2005 Estimation of maximum local scour depth at the bride pier site is necessary for the safety and economy of the designed bridge. Numerous formulae are available and almost all of these formulae were developed based on laboratory data.

Observations of River Topography and Flow Around Bridges [PDF]
, 2009 This investigation was motivated by the amount of river, estuarine, and coastal infrastructure that is susceptible to extreme wave and flooding events. The high velocities and resulting shear stresses associated with high flow velocities are capable of ...

Experimental reintroduction of woody debris on the Williams River, NSW: geomorphic and ecological responses [PDF]
, 2004 A total of 436 logs were used to create 20 engineered log jams (ELJs) in a 1.1 km reach of the Williams River, NSW, Australia, a gravel-bed river that has been desnagged and had most of its riparian vegetation removed over the last 200 years.

Advanced Functional Materials, EarlyView.A 3D nanowire‐network SERS substrate with robust adhesion is developed, featuring pronounced z‐direction optical activity, ultralow detection limit (1.5 × 10−13 M), and excellent signal uniformity (RSD < 10%). Enabled by enhanced light scattering, increased optical density of states, and structural reinforcement, the substrate demonstrates stable, high‐

Local Scour Around The Cylindrical Bridge Pier With Two Sizes of Bed Material [PDF]
علوم و مهندسی آبیاری, 2015 Local scour around the bridge piers results from the flow impact with bridge piers and it’s streamline separation. The scour hole around the bridge piers depend on the hydraulic characteristics of the flow, the specifications of the fluid, the pier’s ...
