Resumo: 	Following lakes and rivers, a lot of estuaries (during the last twenty years) and shallow coastal zones (during the last decade) have been severely eutrophicated because of the too much increasing loads of nitrogen and phsophorus. In situ stutdy and numerical modelling of two french case studies bring some explanation to the facts that, in some sites, enrichment turns into green macroalgal proliferation whereas, in others, mass blooms of phytoplankton are induced. Whatever the case may be, the prominent role of the residence time of water in the enriched zone has been proven. In open coastal ecosystems, the difficulty in determining this residence time as well as the limiting factor (nitrogen, or phosphorus, or light) lowers considerably the reliability of the classical statistical diagrams which have been used successfully in management of eutrophicated lakes. The numerical dynamic modelling provides a promising alternative, which is discussed.
