Groynes in coastal engineering (CIRIA C793), published by CIRIA in 2020, defines cohesive sediment as: ‘Sediment containing significant proportion of clays, the physico-chemical properties of which cause the sediment to bind together.’
It defines sediment grading as: 'Distribution defined by nominal and extreme limits with regard to size or mass of individual sediment grains.'
And sediment transport as: 'The movement of a mass of sedimentary material by the forces of currents and waves. This can be either perpendicular (cross-shore) or parallel (longshore) to the shoreline.'
