Abstract

In this study the SSIIM numerical model has been verified by the experimentally model also the bed topography and three-dimensional velocity components have been compared together. For this purpose the simulation carried out based on experimentally channel model that included the installation of non-submerged T-SHAPE SPUR DIKE vertically (with equal ratio of wing to web length) in movable channel bend, that located in outer bank of 90 DEGREE BEND at 45 degree of bend. The VERIFICATIONs were done in relative curvature equal to 4 and the results compared in longitudinal, cross and vertical sections that express the capable of SSIIM MODEL in determinations of range and maximum SCOUR and sedimentation amounts and also the value of longitudinal and resultant velocities in channel bend or meandering channel. The second SCOUR hole for numerical model formed in downstream of channel in the output of bend and for experimentally model observed in the range between the spur dike and the output of bend. In case of a rigid bed, due to less complexity of flow and non-movable bed, the transverse velocities are much more consistent with the experimentally model compared to the moving bed.
