Cambiamenti idrologici nella Pianura Padana centrale a Nord del Fiume Po: i casi di «underfit streams» dei Fiumi Mincio, Oglio e Adda – Hydrological evolution in the central-northern Po Plain – The underfit cases of Mincio, Oglio and Adda Rivers

Abstract
The evolution of the main ancient rivers in the central Po Plain is presented. The study of the present and ancient hydrography shows the presence of at least three cases of underfit streams. Particularly two parameters are misured: the lenght and the radius of curvature of the meander belts. The data show that ancient hydrography presents geometrical parameters about five times larger than the actual hydrography. Underfit steam marks allow us to know the former discharges and to riconstruct the envinronmental evolution of the central Po plain in the last 15 000 years.
