Abstract

The study of sediment transport generally is very difficult but more so in the case of estuaries because: the water movements are continually changing with the rise and fall of the tide; a wide range of sediment exists on the bed and in suspension; certain sediments are not found in some parts, leading to unsaturated loads in the water. The basic aim of this research was to improve the presentation of sand transporting processes in computer models. The second stage of the project, covered in this report, concentrated on the implications on the suspended load due to the unsteadiness in accelerating and decelerating flow and the numerical simulation of these effects.
