Abstract

Spur dike is a structure that extends transversely from the river bank toward its thalweg and deflects the flows away from the bank toward the center. One common type of this structure is the T-shaped spur dike, and the wings present in this dike can have major effects on the proximate flow pattern. In this study, the turbulent flow around three attracting T-shaped spur dikes placed in series was simulated using the FLUENT, the finite volume method and the k-ε turbulence model. The results of numerical modeling show that increasing the dike length and the spacing between dikes both alter the flow pattern around the structure, but flow pattern is more affected by the increase in the dike length than by the increase in the dike spacing.
