[automatically translated] The survey has tested the applicability of the BEST method of soil hydraulic characterization in a site placed upstream of the town of Giampilieri, where in 2009 there was a catastrophic flood event. The surface layer of the soil showed eluvial features while the deeper (-0.30 m), appreciably more compact and less permeable in saturated conditions, and with a higher clay content, presented the characters of an illuvial layer. The results of measurements have suggested the possibility of the formation, during the events meteoric intense and prolonged, of a suspended water table and the development of positive pressures that contribute to instabilizzare the surface layer of soil.
