The prediction of scour evolution at bridge foundations is utmost importance for engineering design and infrastructures’ safety. complexity the scouring inherent flow field result separation generation multiple vortices further magnified due to dynamic interaction between movable bed throughout development a hole. In experimental environments, current approaches characterization rely mainly on ...

Bridges are built to facilitate transportation between the two banks of rivers and waterways. They usually supported by piers with geometric shapes that differ from one bridge another, such as a complex pier. Due intersection water flow, many vortices generated, causing local scour around piers. Local is affected factors, including geometry other hydraulic factors. In this study, number laborat...

Abstract The local scouring around the pier, is one of major cause bridges failure worldwide. Compared to flow hydraulics in single channels, pattern compound channels completely different with flood plains covered vegetation and this issue can affect amount area bridge piers. However, combined effect these factors has not been systematically investigated. Therefore, due complex nature phenomen...

River slopes can be changed due to an extreme event, e.g., a large-scale earthquake. This uplift riverbed greatly and thereby change the behavior of river flow into free or submerged overfall. Corresponding damage, including erosion, on bridge piers located in take place aforementioned conditions. A reconstructed pier same location would also experience similar impact if condition is not change...

In this study, the scour depth and dimensions of hole around different shaped piers for cases hydrographs succeeding steady flow were studied experimentally. The experiments carried out by using circular, square, rectangular, lenticular rectangular with trapezoidal nose to compare various geometries at same conditions. Numerous conducted in a flume (18.6 m long, 0.80 wide 0.75 deep) triangular ...
