Fig. 3

Digital Elevation Models (DEMs) of the Var valley and a representative topographic profile across the Donaréo valley. a DEM of the Var valley, with slope coutour values according to the chart to the left of the figure, below the map. b Enlarged DEM of a symmetrical watershed (south of Colomars). c Enlarged DEM of an asymmetrical watershed (Donaréo valley). d Topographic profile across the Donaréo valley (the location of the section is shown on a). DEMs are shown with red shading in the zones of abnormal topography, emphasized by high slope values (>40°), mainly along the Donaréo valley. Note the strong influence of the fault runoff in the Donaréo valley on the secondary water drainage system. The topographic signature of the fault is also emphasized by the AB cross-section drawn across the strike of Donaréo valley, below the maps
