Verification of a three-dimensional numerical model simulation of the flow in the vicinity of spur dikes

The objective of this paper is to show the results of simulations of the flow near spur dikes using a three dimensional numerical model. Special attention was given to the simulation of the wake formed downstream of the dyke and the influence of the eddy viscosity field on velocities, flow depths and reattachment lengths. The most important features of the model are described. Comparisons with flume measurements conducted at the Franzius Institute in Hannover, Germany are also presented.
