This paper describes how morphometric classification (based on openness, form, depth and size) and
Geographic Information Systems (GIS) can be used for possible identification of coastal areas sensitive to pollution.
Generalized maps of key water properties are then created for as large parts of Europe as possible using large amounts of
empirical data. These maps give an overview of the general spatial pattern of the presented properties and offer
identification of highly polluted coastal areas. They also provide input and reference data for two dynamic ecosystem
models (CoastWeb and CoastMab) suitable for in-depth studies of individual coastal areas or regions. A modeling case
study of coastal eutrophication is presented to illustrate that these general models may be practically applied for
simulations related to the response of coastal ecosystems to various remedial scenarios using only the data presented in
the morphometric coastal classification system and in the generalized overview maps.
