Sediment Transport in Dredged Trenches
Publication: Coastal Engineering 1992
Abstract
An attempt was made, using a 3-dimensional turbulent model coupled with a comparatively simple depth averaged sand transport model, to assess the computational feasibility of predicting sediment transport in a dredged trench, caused by a steady flow passing across the trench. A sophisticated computer software package was used to simulate 3-dimensional turbulent flow by the finite element method. A Profile Model, which discretized the transport process to enable sucessive computation of the flow field, was used for morphological evolution of the channel bed. A physical model was built and tested to validate the numerical models.
