Abstract: This technical note reassesses the prevailing understanding of lateral-contraction scour at bridge waterways. Herein, lateral contraction (or simply contraction) implies a reduction of flow width. Nonuniform flow to and ...

Abstract: This paper presents observations on clear-water and live-bed contraction scour caused by subcritical flow along a large rectangular channel. Three contraction ratios (contraction width/approach–channel width) were used: ...

Abstract: This paper presents insights from two small flumes used to compare ice conveyance and jam initiation between straight and sinuous channels of rectangular cross section, and to investigate ice accumulation and jam morphology ...

Abstract: Scour at bridge abutments usually consists of local and contraction scour that correlate because of the flow field that develops both scours. Flume experiments were conducted using simulated compound channels to investigate ...
