Development of a Computer Model for the Prediction of Littoral Sediment Transport Rate
Author
Abstract
In this paper, longshore sediment transport in littoral zones is investigated. For investigation of sediment transport in the nearshore zone, the effects of waves, currents and topographical conditions of coast are considered. Linear wave theory was used for the investigation of the wave behaviour. Governing equations of littoral current are continuity and momentum ones. For calculating concentraion profile of suspended sediments at depth, the convection-diffusion equations must be solved.
A computer program called “PLSTP” (Prediction of Sediment Transpornt in Littoral Zones) is developed for investigation of sediment transport process in littoral zones. The finite difference method is used for solving governing equations. The results show a good agreement between this model and the measurements available.
