ABSTRACT
Sediments are fragmented material, primarily formed by the physical and chemical disintegration of rocks from the earth’s crust; they can be divided into cohesive and non-cohesive sediments. For non-cohesive sediments there are no physical-chemical interactions between individual particles and the size and weight of an individual particle are important factors in their behaviour. In cohesive sediments the physical-chemical interactions between particles are important factors in the initiation ofmotion (erosion) and also in the transportation (flocculation); with cohesive sediments the size and weight of a particle have less significance. Most of the discussion on sediment transport in these lecture notes will deal with non-cohesive sediments.
