Transport of sand mixtures - a literature review (SR 200)

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;
a wide range of sediment exists on the bed and in suspension.
The first phase of this project included a literature review of the transport of sand mixtures including consideration of field data, threshold of motion, fall velocity and bed, suspended and total load transport. This report summarises the main references on the subject and contains a brief description of the latest theories being considered by other workers in this field.
