The European Watershed-Coastal Zone Integrated Study (EWCZ), launched as a pilot project for the period 1999-2003, is made up of two separate but closely integrated activities: a European Scientific Coastal Observational Network (ESCON) and a European Watershed Observational Network on Soil and Water Pollution (EuW ASP).

The objectives of the EWCZ project were to:
- Determine the long-term changes of selected European river basin-coastal zones at local, regional and continental scale as well as identify and quantify the effect of current anthropogenic activities on these linked ecosystem in the context of their natural variation;
- Determine the natural capacity of coastal ecosystems to assimilate nutrients originating from land-based sources;
- Estimate the level of nutrient reduction required to protect water quality and living resources from human induced nutrient changes.

The present study is a part of a series of case studies, where an integrated approach coupling the watershed and the coastal zone, in this case the Thau coastal lagoon, has been developed. This is necessary in order to take properly into account the influences of river basin runoffs on the dynamics of the coastal ecosystem. The first step, summarised in this work, was the modelling of the Thau watershed.
