Abstract

INTRODUCTION: THE STUDY OF BED-LOAD TRANSPORT IS VERY ESSENTIAL FOR VARIOUS HYDRAULIC AND ENVIRONMENTAL PROBLEMS IN COASTAL ENGINEERING DISCIPLINE. THE MODE OF TRANSPORT IS A FUNCTION OF THE BED SHEAR STRESS, WHICH MAY OCCUR IN SALTATION OR SHEET-FLOW. FROM LOW TO MEDIUM FLOW TRACTIVE FORCES THE BED-LOAD TRANSPORT OCCURS IN SALTATION, IN WHICH THE UPPER LAYERS OF BED GRAINS BEGIN TO MOVE DUE TO DRAG FORCES INITIATED BETWEEN THE FLOW AND SEDIMENT. ON OF THE MAJOR CHALLENGE IN FRONT OF THE COASTAL ENGINEERS IS TO SIMULATE THE BED-LOAD TRANSPORT DUE TO COASTAL CURRENTS IN NEARSHORE AREA. ON THE OTHER HAND, THE NUMERICAL MODELING OF BED-LOAD TRANSPORT IS VERY COMPLICATED BECAUSE OF ITS HYDRODYNAMIC PROCESS. THIS HYDRODYNAMICS PROCESS USUALLY CAN BE EXPRESSED BY THE FLUID-SEDIMENT INTERACTIONS AND INTERGRANULAR STRESSES.
