The Multidisciplinary Approach in the Study of Landscape Evolution: The Fluvial Capture of the San Donato Creek (Gubbio, Central Italy), an Example of Hydrological Regime and Hydrogeological Risk Changes

Historical maps, especially those at a small scale and rich in detail (e.g., the old “Cadastres”), represent an exceptionally important tool for understanding recent historical evolution of landscapes. The note describes example territory Gubbio, Umbria (Central Italy), where map from end 16th century shows drawing hydrographic network partially different current one. A multidisciplinary study based on field surveys, observations satellite images, archaeological discoveries, archival research proved useful to confirm what was reported by cartographer time. possible causes that led this variation surface hydrography up its configuration are then discussed light other documentary finds archives, taken chronicles time, which have made it identify, with sufficient approximation, period change occurred. All leads highlighting profound fluvial slope morphogenetic processes affected area centuries, regulation waters afforestation, conducted during 20th century, played decisive role.
