Description :
17 alluvial fans in Po Plain, between the Ticino and Mincio Rivers, in Northern Italy were identified and studied. The research was carried out following a semi-quantitative approach that combined display and analysis of altitude data, interpretation of morphometrical maps, and comparative inspection of geomorphological maps. Boundaries between fans were drawn interactively on a shaded relief image, computed from a 50 m resolution digital terrain model prepared interpolating 5 and 1 metre contour lines. The relationship between fan area and drainage basin area shows positive allometry.
