This chapter provides descriptions of essential features of modelling of a broad range of problems involving many classes of sediment, flow, applications and research top¬ics. The experimental reproduction of hydraulic processes involving sediment dynam¬ics is focussed on the sediments and not the hydrodynamic processes, which are covered in other chapters. Since a great deal of experimental research on sediment dynamics remains to be done, laboratory experiments to elucidate process knowledge (research) as well as physical modelling of site-specific applications (consultancy) will be covered
