Transport of sand mixtures - formulation and development of a computer model - contract completion report

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, certain sediments are not found in some parts, leading to unsaturated loads in the water and a wide range of sediment exists on the bed and in suspension. The purpose of the present research project was to consider the problems associated with mixtures of sediment and to develop a method for computer simulation of the important physics of sand mixtures. The objective was a predictive model for engineering applications rather than a scientific model of the detailed processes.
