Transversal Sediment Transport in Straight Sandy Rivers with Bank Vegetation

Abstract

Non-steady process of transversal sediment transport in a straight sandy rivers with bank vegetation was experimentally investigated. Location of sediment deposition in a vegetated zone was determined by vegetation density, and it spreads to faraway region from the interface between vegetated and nonvegetated zones with decrease in vegetation density and with time. Thus, deposition rate of suspended sediments in the farway region increases relatively with time. In addition, a concentration profile of suspended sediments also varies with time corresponding to change in sediment suspension and deposition.
