This study focused on two small watersheds belonging to a network of watersheds defined and followed by the IRD-Tunis within the framework of the AMBRE program. The importance and complementarity between photo-interpretation and ground techniques are emphasized in this work. This article offers answers to certain questions concerning landscape matters by approaching them from the “Science of the landscape” point of view, here meaning the hydrodynamic segmentation of the landscape. The study aims at delimiting and better understanding the organization of landscapes in segments and their hydrodynamic behaviour at the level of the watersheds, as well as the global impact of development on these surroundings. We ask how the landscapes are organized, what their hydrodynamic behaviours are, the impact of development in these Mediterranean surroundings and whether the notion of landscape segmentation, derived from the method of “Science of the landscape,” is pertinent to furthering the understanding of these landscape dynamics.
