Flow Structure at Different Stages in a Meander-Bend with Bendway Weirs

摘要: Streambank erosion is an important management issue, particularly for meandering rivers. Recently, bendway weirs have become popular control measures bank along small streams in the agricultural Midwest. Although these structures successfully mitigated some cases, there evidence that do not always perform as anticipated. Scientific understanding of how influence flow dynamics, streambank erosion, and aquatic habitat limited. Current design criteria are based primarily on expert judgment rather than a formalized technical procedure. At field-scale studies, present paper represents first step toward integrated geomorphological engineering evaluation performance To accomplish this initial phase, three-dimensional (3D) velocity data were collected Sugar Creek at Brookside Farm, Ill., 3D numerical simulations low-flow conditions performed to validate computational...
