This paper presents the results of a newly developed computer simulation model for studying the sedimentation processes in a variety of hydrosystems. The most effective numerical methodology and the most reliable empirical functions available are applied to attack this complex problem. The soil sediment transport in a hydrosystem is represented by a mixed dimensional, computational model, which contains one-dimensional, two-dimensional and three-dimensional elements. Different subdomains are represented by the appropriate elements to achieve the best possible computational efficiency. This paper focuses on the newest part of the system, the three-dimensional domain. The test case presented consists of a channel bend with relevant secondary flow.
