Abstract: - Geomorphological conditioning of rural and urban development in Satu Mare County. The interaction between the human and the geomorphological component involves specific aspects, due to the high intensity of the interferences between the two components, despite the relatively short period of time when they have taken place. The manner of materialization of these interactions has been directly influenced by the favourable or restrictive characteristics of the relief, manifested through the mediation of static (locational) or dynamic featuresThe geological, morphometric, climatic and land use features determined the manifestation of a large range of geomorphological processes in Satu Mare county. The type, intensity and manner of action of these processes reflects the way in which the environmental components relate between each other. The quantitative assessment of the stability of geomorphological areas as the landslides are concerned has been accomplished according to a computerized algorithm based on the model of infinite stability of slopes, conceived by relating the forces which tend to undermine the stability of the slopes (gravity) and the ones that maintain the stability (the force of friction and the cohesion of rocks). The main result of this working algorithm is the stability index, defined as the probability for an area to be stable in relation to the mass movement processes, when the parameters are equally distributed. The values obtained from the computerized analysis have been grouped into 5 stability classes.

Key-words: restrictiveness, settlements, landslides, stability index
