Abstract Local scour that occurs around the bridge pillars affects significantly the stability of the bridge superstructure, where it will generate the bridge structure failure. Modifications the geometry of the bridge pillars is one of the effort

Harvesting the river materials can cause negative effects on the river and can intensify scouring around the bridge piers. This study investigates local scouring around roughened pile groups with gravel in the presence of harvesting pits for Froude n

Abstract. Water flowing in the river causes a scouring event that occurs at the bed channel. The existence of scouring will increase along with changes in the geometry of the river and obstacles such as the weir which are followed by local scouring a

Given that the development of scour downstream of hydraulic structures increases the risk of structural damage, it is important to find cost-effective and environmental approaches to reduce this risk. This study aimed to experimentally evaluate the e

Bridges are one of the most important and widely used river structures. Every year, a large number of them are destroyed by factors such as scouring and erosion. It is sometimes observed that the bridges are placed in the river bend, due to restricti

Bridge pier's local scouring is known to be a destructive factor in river engineering science. This phenomenon is widespread in river intersecting structures such as bridge piers, spur dykes, and downstream river structures. Extensive research has be
