Characteristics and mechanism of local scour reduction around spur dike using the collar in clear water [PDF]
Scientific ReportsTo reduce the local scour around the spur dike, the U-shaped collar is proposed in this study. The influence of the collar's length, width, and porosity on the local scour reduction in clear water is studied by model tests and numerical simulations ...

Turbulent Kinetic Energy Distribution around Experimental Permeable Spur Dike
Sustainability, 2022 The spur dike is widely used in the waterway renovation project in the upper reaches of the Yangtze River as a remediation structure, but its water destruction is very common, and the influence of the permeable characteristics of the riprap spur dike on its stability has been neglected in many studies.

Three-Dimensional Flow Characteristics in Slit-Type Permeable Spur Dike Fields: Efficacy in Riverbank Protection [PDF]
Water (Switzerland), 2020 This paper focuses on finding efficient solutions for the design of a highly permeable pile spur (or slit type) dike field used in morphologically dynamic alluvial rivers. To test the suitability of different arrangements of this type of permeable pile spur dike field, laboratory experiments were conducted, and a three-dimensional multiphase numerical ...
