Failure of bridges due to local scour has motivated many investigators to explore the causes
of scouring and to predict the maximum scour depth at abutments. In this paper, a detailed …

Prediction of scouring characteristics is one of the major issues in hydraulic and hydrology
engineering. Over the past five decades, numerous empirical formulations (EFs), based on …

Development of local scour depths at vertical-wall bridge abutments of varying lengths was
investigated in several series of experiments of ranges of uniform sediments and clear-water …

A semiempirical model is presented to compute the time variation of scour depth in an
evolving scour hole at short abutments (abutment length/flow depth⩽ 1), namely the vertical …

Scour is one of the most difficult challenges faced by hydraulic engineers, which refers to the
erosion of sediments that surrounds hydraulic structures. In the past, scour prediction has …

Experiments on clear-water scour below underwater pipelines (initially laid on the sediment
bed) in uniform and nonuniform sediments under steady flow were conducted. Equilibrium …

Bridge piers having a nonuniform cross section over their height are termed as compound
bridge piers. Mostly circular piers resting on large diameter wells or caissons (termed here …

This study presents the effect of different parameters on the scouring process around spur
dikes. Our research group's stated objective was to evaluate the effects of sediment …

Accurate prediction of the local scour at abutments is an important criterion to design a safe
depth for the bridge foundation. In this paper, the dimension and variation of local scour with …

Local scour around bridge abutments is a widespread problem that can result in structural
failure. Collars can be used as a countermeasure to reduce the scour depth. In this study …
