RISEffects of Upstream Weir Slope on Local Scour at Submerged Weirs
Publisher: American Society of Civil Engineers
Abstract: The variation of upstream slope of a submerged weir could significantly alter the local flow pattern and sediment transport. This paper presents an experimental investigation into local scour at submerged weirs with different ...
Unified Formula for Critical Shear Stress for Erosion of Sand, Mud, and Sand–Mud Mixtures
Publisher: American Society of Civil Engineers
Abstract: Research on erosion behavior of sediments usually treats sand and mud separately. However, natural soil often occurs as a sand–mud mixture. An expression for cohesive forces in sand–mud mixtures, which considers the effect ...
Local Scour at Downstream Sloped Submerged Weirs
Publisher: American Society of Civil Engineers
Abstract: This paper presents an experimental study of local scour at submerged weirs with different downstream slopes. Thirty-three tests of coarse sand (d5=.85 mm) and 24 tests of fine sand (d5=.26 mm) were carried out in a ...
Flood Inundation-Induced Bridge Pressure Scour: Developing New Prediction Equations and Exploring Machine-Learning Methods
Publisher: American Society of Civil Engineers
Abstract: AbstractBridge pressure scour occurs when the bridge deck is inundated during a flood event,
causing significant threats to the stability of local streambeds and bridge foundations.
In the present study, new flume experiments ...
Clear-Water Local Scour at Skewed Complex Bridge Piers
Publisher: American Society of Civil Engineers
Abstract: An experimental study on flow-induced clear-water local scour at complex bridge piers was conducted using two typical pier models, nine pile-cap elevations, and seven pier skew angles from ° to 9° with a 15° interval. ...
