Abstract

Spur dikes are the intersecting or transverse structures, which are projected from the river bank toward the flow axis and cause diversion and direction of the flow from the banks towards central axis of the river. This structure affects the flow lines and causes change in the river flow pattern and protects the banks against erosion. Recognition of the flow pattern around a spur dike could help in a better understanding of the scour pattern and, as a result, achieving an accurate value of maximum scour depth. In this study, the k-ε turbulence models are investigated in determining the rotational flow and flow field around the spur-dike using FLUENT software. The results show that the software incorporating the k-ε model could appropriately model velocity distribution around the spur dike and the results exhibit a good compatibility with an average error of 9.24%.
