The Argentine subtropical plains are characterized for a very low relief amplitude. They supports continuos drier and floodings periods which are caused by intense rainfalls or large river floods. In order to detect the risk areas, the geomorphology constitute one of the main scientific tools for this study. This discipline is related directly with civil works (dams, bridges, buildings, railroads, etc.) and the spatial organization. The aim of this paper is to describe the main géomorphologie features and the influence of natural risks that overcome either cattlerising, urbanization, farming, civil work areas. In the paper, we remark the importance of the aerial photographies and the satellite imageries applied to géomorphologie tasks. The importance of these tools is its relation to the thematic mappings. On the other hand, it is analyzed the effect of the paleogeomorphology, altogether associated to oscilating climatic conditions not similar to the actual ones. Finally, the objective is to have in mind the analysis of serious risks originated by the global climatic change and the anthropic action which are actively acting over the large Argentine plains in the last decades.
