In the framework of several projects sustained by the Regional Sardinian Government Laws no. 43 (28/09/1990) and no. 19 (11/04/1996), research groups of the University of Cagliari (Sardinia, Italy) and of the University Mohamed V-Agdal of Rabat (Morocco) have started a series of preliminary geo-environmental studies in the basin of the Oued Sebou. An area of almost 1000square km around the famous city of Fe's has been studied, using satellite images and two ground surveying campaigns. These surveys aim to define the geological and structural settings, the vegetation and land use, in order to define the landscape units and to select the areas of major hydrogeological and geo-environmental risk. The satellite data used are the LANDSAT TM5 images taken on the 9th of October 1997. These images have been analysed to obtain the different bases for further thematic mapping, resulting in the geo-environmental map of the area around Fe's that constitutes an up-to-date representation of the geological and environmental state of the territory and a useful instrument for further risk assessment and urban and territorial planning. © 2004 Elsevier Ltd.

Abstract
In the framework of several projects sustained by the Regional Sardinian Government Laws no. 43 (28/09/1990) and no. 19 (11/04/1996), research groups of the University of Cagliari (Sardinia, Italy) and of the University Mohamed V-Agdal of Rabat (Morocco) have started a series of preliminary geo-environmental studies in the basin of the Oued Sebou. An area of almost 1000square km around the famous city of Fe's has been studied, using satellite images and two ground surveying campaigns. These surveys aim to define the geological and structural settings, the vegetation and land use, in order to define the landscape units and to select the areas of major hydrogeological and geo-environmental risk. The satellite data used are the LANDSAT TM5 images taken on the 9th of October 1997. These images have been analysed to obtain the different bases for further thematic mapping, resulting in the geo-environmental map of the area around Fe's that constitutes an up-to-date representation of the geological and environmental state of the territory and a useful instrument for further risk assessment and urban and territorial planning. © 2004 Elsevier Ltd.
