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.
Monitoring coastal morphodynamics is of importance when for example coastal erosion of accretion is present or protective measure are taken and the effectiveness of these measures need to be known. Monitoring this process in time is of importance to manage the developments in the right way. A technique to do this is by high-precision multibeam technology. This technology is explained in this article and an example of application is given. This shows how high-precision multibeam technology can be used in practice.

[[Coastal erosion]], [[bathymetry|bathymetric]] changes of the near coast seabed or the stability and dispersal of dredged and disposed material are among the key questions of [[coastal management]]: What are the effects of [[coastal protection]] measures? How effective are they? Do they generate new burdens on the coastal system? Which processes control the movement of the seabed? What are the typical scales for the rearrangement of bed material? What types of seabed structures contribute most to the transport of the bed material? To what extent are morphological changes predictable?
 
Answers to these questions are still limited by a lack of observational evidence. Most of all, area-wide data are required to allow for comprehensive views of the relevant bed structures ranging over horizontal scales from decimetres to kilometres. The detection of seabed changes over these wide ranges of scales requires observational systems that combine high spatial resolution down to decimetres with high precision and accuracy in the horizontal and vertical positioning of the seabed structures in the range of centimetres.

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.
