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.
