The hydrodynamic conditions or processes, that come about from [[Tidal wave|waves]] transforming over a coastal profile and generating wave set up and [[Longshore current|longshore currents]], will result in movement and transport of the sediments (e.g. sand) present in the profile. This is referred to as ''littoral transport processes'' and is the main subject of this article. However, transport of fine sediments will also be discussed, but only very briefly.

The sediment on the seabed is transported when it is exposed to large enough forces, or ''shear stresses'', by the water movements. These movements can be caused by the current or by the wave orbital velocities or a combination of both, the latter being the most important situation. The relevant parameters for the description of the sediment transport along a shoreline or in a coastal area are therefore the following:
 
−
 
 
−
*The wave conditions at the site and the possible variations over the site plus the adjoining areas
 
−
*The current conditions as well as the variations of these over the area
 
−
*The water-level conditions, i.e. tide, storm surge and wave set-up
 
−
*The [[bathymetry]] (the depth variations) in the area
 
−
*The [[sediment]] characteristics over the area
 
−
*The sources and sinks of sediment, such as rivers, eroding coasts or tidal inlets

Compendium for Coast and Sea - creating a marine science-policy interface


The Compendium for Coast and Sea is an integrated knowledge document about the socio-economic, environmental and institutional aspects of the coast and sea in Flanders and Belgium. As such, it constitutes a one-stop shop for data and information from the Flemish and Belgian marine and maritime research community and experts. The Compendium for Coast and Sea is an initiative of the Flanders Marine Institute (VLIZ) and was developed in close collaboration with experts from the research community, government, industry and civil society organisations. The first version of the Compendium was launched in 2013, a second edition was presented in 2015.
