Abstract

Bridge pier scouring may lead to bridge failure, and one of the major factors in minimizing scour around the pier is the shape of the pier itself. This study investigated the effects of bridge pier nose shapes (rectangular, oblong, and triangular) and nose properties (solid and gabion) on scouring around the bridge pier. A uniform bed material with a median size (d50 = 0.52 mm) and a standard deviation (σg= 2.35) was employed. The results showed that the triangular shape has more satisfactory results in reducing scour compared to other shapes of the pier. The results revealed the effectiveness of the gabion-nosed piers in decreasing the maximum scour depth, results indicated that about a 46% reduction in scour depth was obtained due to using the pier with a gabion nose for used pier models. The study results may be applied in the area of applicability for bridge pier protection design.
