“…Andries Vierlingh wrote the first scientific tractate, Tractaete van Dyckagie, dedicated to groyne design in the Netherlands around 1576. Although groyne design has attracted a considerable amount of scientific interest (Brinkmann and Holtz, 1990;Mayerle et al, 1995;Ouillon and Dartus, 1997), few studies have examined the recirculating flow between sequential groynes and the consequences for the exchange and deposition of particulate matter in the groyne fields (Carling et al, 1994;Uijttewaal et al, 2001).…”

This paper examines a variety of recirculation flow patterns that develop in the groyne fields on rivers. A comprehensive data set was obtained from flume experiments at Delft University of Technology and field measurements performed on the Elbe River in Germany. The analysis focuses on patterns of velocity, scour and deposition, and corresponding change of riverbed morphology. The results show that velocity patterns in the groyne fields depend mainly on the aspect ratio between groyne length and length of groyne field. When the aspect ratio is greater than 0Ð5, a one-gyre pattern of recirculation develops, while at groyne fields with aspect ratios less than 0Ð5 a two-gyre recirculation pattern emerges. The spatial distribution of fine-sediment deposition between the groynes coincides with the locations of gyres. Moreover, the thickness of the fine-sediment layer decreases toward the gyre margins where recirculation velocities are greatest. Although the total concentration of suspended sediment in the river does not change considerably as the flow moves through the groyne field, the biological and gravimetrical composition of the suspended material changes substantially within the groyne field. These changes are due to preferential deposition of coarse mineral particles and the replacement of those minerals with finer organic material.

“…Depending on the physical nature of #ows and the zone of interest within the #ow domain, certain problems require the use of 3-D models (Ouillon & Dartus 1997;Mayerle et al 1995;Hafez 1995). The 2-D models are appropriate for applications involving simpli"ed #ow regions (Bravo et al 1996;Molls & Chaudhry 1995;Kimura & Hosoda 1997).…”

“…Since the flow near a spur-dike is very complicated, the 3D modelling has been applied [9,8]. However, it does not seem that 3D modelling is quite useful in engineering practices because of choice of turbulence closure, treatment of changing geometry due to erosion and sedimentation and computational expenses.…”

This paper presents a numerical model to simulate two-dimensional flow near a spur-dike. The Computational Fluid Dynamics (CFD) program namely Nays 2D has been used to simulate the flow field in a fixed flat bed around the spur dike introduced into the flow at 90° to the stream-wise direction. Cubic-Interpolated PseudoParticle (CIP) method was used as finite difference method to analyze the advection terms. In addition, several turbulence closurer models k-ε model, zero equation model and constant eddy viscosity model were applied and compared in order to achieve the best result. The simulated results were compared with existing experimental and computed data which agreed satisfactorily. Achieved results can prove that flow structure simulation around a spur dike could be done by Nays 2D numerical modelling very well.
