Abstract
The Finite Element method gained remarkable popularity during the last decade in Fluid Mechanics, because of its great flexibility, required to modelise complex domains found in nature.The authors present a two dimensional Finite Element model of bed load. transport, which allows simulation of spatial-temporal variations of bed profile. The formulation is fully discussed, including remedies introduced to treat unsymetrical diffusion leading to unrealistic bed profile evolutions. A flume experiment, related to bed profile evolution near a spur-dike has been undertaken in order to validate the present model.
