Abstract: 

INTRODUCTION: 2D-DEPTH AVERAGED NUMERICAL MODELS HAVE BEEN FREQUENTLY USED IN PROBLEMS OF RIVERS AND SHALLOW WATERWAYS IN RECENT YEARS. FOR RIVER BENDS WITH A MEAN RADIUS-TO-WIDTH RATIO OF BIGGER THAN 3.0 (R/W>3.0), WE CAN SUPPOSE FLOW EXHIBITS 2D CHARACTERISTICS. SEVERAL RESEARCHERS HAVE DEVELOPED 2D, DEPTH AVERAGED MODELS FOR HYDRODYNAMIC MODELING OF RIVER FLOW.
SIMULATION OF CONTAMINANT DISPERSION IN RIVERS AND WATERWAYS IS ONE OF THE INTERESTING RESEARCH TOPICS RECENTLY. DUAN (2004) DEVELOPED A HYDRODYNAMIC AND CONAMINANT DISPERSION MODEL [11]. SHE USED A CARTESIAN GRID FOR HER MODEL. THE MAIN DRAWBACK OF USING CARTESIAN MESH IS ITS SHORTCOMING IN MODELING OF PERIMETERS ACCURATELY IN CURVED WATERWAYS.
