Several approaches, including fieldwork, numerical modelling, and laboratory physical models, are used for studying flow and sediment transport in river systems. Each approach has its advantages and limitations. 

Physical (scaled) models remain a very useful tool, widely applied by engineers for a broad spectrum of applications (e.g., design of hydraulic structures, river restoration works). Form-process-response interactions can be replicated intrinsically, provided a sound design of the physical model combined with accurate laboratory measurements. This is especially true when studying flow and sediment transport with local three-dimensional (3-D) features in complex geometries near structures (e.g. dams, weirs, groynes). Using physical models, the fluvial processes can be observed in a reduced time-frame, within a controlled and manageable laboratory environment. The basic aim is to ensure that the relative magnitudes of all dominant processes and their associated sediment response are the same in the model and prototype.

Similarity laws for sediment transport are far from unanimous. Sediment transport processes continue to pose a challenge when designing movable-bed physical models. Th aim of this short course is to share knowledge and gaps on the hydraulic and sediment transport scaling theory (rigid or moveable beds). Apart from the theoretical background, concepts are illustrated by various engineering applications.

It is expected that the participants have basic knowledge of river hydraulics and sediment transport.  The participants are asked to bring their computers to be able to follow the hands-on exercises and get acquainted with the concept application.
