Résumé
The present master’s thesis, had as its main objective the application of a dynamic model of riparian habitats in a case study with pronounced mediterranean characteristics. he vegetation model used is based on the existence of water conditions (water height and distance to water) suitable for the development of each type of riparian vegetation in different stages of their development, modeling annually its space-time evolution. The rules underlying the model take into account the height of the flow, the shear stress and duration of flooding. The modeling of vegetation held in ArcGIS environment, bases on three general ohases : initial creation of landscape, simulation of temporal and spatial evolution of vegetation and the presentation of annual results.

Mots clés : riparian vegetation climatic change hydric regime modeling vegetação riparia alterações climáticas regime hidrológico modelação
