Abstract
    Development and description of the polderlandscapes along the Scheldt river north of Antwerp are given: the land is subdivided into Ancient-, Flood- and New Land (Oudland, Inbraakland, Nieuwland) and bordered along the Sandy Region by a transitional area (Randgebied) . From the study of sites appears that most of the villages and many farmsteads are not located in the polder proper (pseudopoldersites), but on pre-alluvial rims or islands (donken). Some of these "donken" have been locally covered by a thin layer of alluvial deposits and have maintained a slightly elevated position (overdekte donken). They are considered as a transitional type between the pseudopoldersites and the true poldersites. In the Floodlandpolders, where "donken" occur exceptionnally, the habitat has avoided the heavy claysoils (schorsites) and is mainly developed on the more sandy deposits of the reclaimed foreland ( schorwalsites). Minor differences in the constitution and topography of this foreland made a further subdivision of the forelandsites possible. The numerous floods that have ravaged the polderland, have favored the attraction of habitat along the backside (achterdijksites) and on the dikes (dijksites). Location along the backside of a dike has been advantageous with regard to the use of the fordying saltmarsh, while location on a dike has often been the result of a provisional settlement by people who had left their home and land during inundations. It is commonly admitted that the habitat in the polders of the Scheldt river is of the dispersed type. We found that it varies from dispersed to concentrated in function of the size and distribution of same well-defined sedimentary units, having particular topographical and hydrological caracteristics that influenced the location of most of the sites in a decisive way.
