Abstract

INTRODUCTION: PARTICLE MOVEMENT WILL TAKE PLACE WHEN THE INSTANTANEOUS FLUID FORCE ON A SEDIMENT GRAIN IS JUST LARGER THAN THE INSTANTANEOUS RESISTING FORCE [1]. IN ORDER TO CONSIDER DIFFERENT HYDRODYNAMIC FORCES WHICH EXERT ON THE GRAIN, NEWTON’S SECOND LAW CAN BE UTILIZED IN A LAGRANGIAN PERSPECTIVE. A NUMEROUS STUDIES WERE CONSIDERED SUCH WAY FOR THE NUMERICAL SIMULATION OF THE DIFFERENT REGIMES OF THE SEDIMENT TRANSPORT INCLUDING SALTATION (E.G. [2], [3], [4], [5]). HOWEVER, THE INCIPIENT MOTION OF THE SEDIMENTS GRAINS HAVE NOT YET BEEN STUDIED, EFFICIENTLY. THE PRESENT STUDY FOCUSED ON THE DEVELOPMENT OF A 3D LAGRANGIAN NUMERICAL MODEL USING DISCRETE ELEMENT METHOD FOR PREDICTING THRESHOLD OF SEDIMENT MOTION...
