5TAKING INTO ACCOUNT THE EFFECT OF SECONDARY FLOWS IN DEPTH AVERAGED MORPHODYNAMIC SIMULATIONS显示文摘Due to centrifugal forces in a bend secondary currents perpendicular to the main flow are generated. Because they can be the reason for important bed forming processes such as meandering they have to be taken into account in morphodynaniic simulations. Their influence on the bed shear stress is proportional to the ratio of water depth and curve radius. The latter one is a curve parameter and is not defined in 2D digital terrain models. This paper presents a new formulation for the bed shear stress which takes into account, the influence of secondary currents in depth averaged simulations without using the curve radius. The new formulation is applied to a morphodynanuic model of the Weser estuary located in Northern Germany. Its capability to simulate the deflection of the bed shear stress in bends is shown. Because of the smoothness of the curves in the Weser no significant differences in the bed evolution can be seen in this case.Andreas MALCHEREK 1 Research Engineer, Federal Waterways Engineering and Research Institute (BAW), Coastal Department, Wedeler Landstr. 157, 22559 Hamburg, Germany. 2001International Journal of Sediment Research2001,16,2:1
6APPLICATION OF BED EVOLUTION MODELS OVER LOOSE AND RIGID AREAS显示文摘This paper discusses the abilities of numerical models to predict the morphodynamics over loose and rigid ho. In the papers first part the model TSEF is presented which solves the bed evolution equation in conjunction with sediment transport formulas. The flow field and the water wepth are calculated using the dept-averaged hydrodynamic model TELEMAC-2D. In the second part algorithms to simulate unsaturated sediment transport over rigid beds are presented. The problem of how to calculated the transport rate in the transition zone is posed. Finally the model is applied to an estuarine tributary.Andreas MALCHEREK Research Engineer, Federal Waterways Engineering and Research Institute (BAW), Coastal Department, Wedeler Landstr. 157, 22559 Hamburg, Germany 1997International Journal of Sediment Research1997,12,3:0
