Piedmont Region, in North-Western Italy, extends for approximately 25,400 square kilometres and represents the more western part of the Po Plain. About 43% of its territory is constituted by mountains, 30% by hills while the plain covers 27% of the whole territory. The Piedmont plain is the most important water reservoir of the Region because of its size, the features of its deposits and the possibility to recharge.
A hydrogeological map of Piedmont plain (scale 1:300,000) is presented, which summarises about twenty years of research in the area. The main hydrogeological units are shown with an indication of their type and degree of permeability. The piezometric map of the shallow aquifer in plain, referred to summer 2016, is reported, highlighting the main groundwater flow directions. Other information are also presented, namely the map of depth to water table, the map of permable deposits (0-50 m from the ground surface) and litostratigraphic cross- sections.
Moreover, time plot of piezometric level fluctuations in representative monitoring wells are provided. More specifically, monthly average piezometric level in the period 2002-2017 was analysed, describing different hydrodynamic behaviour of the groundwater table in the Piedmont Plain.
This map wants to represent an overview of the hydrogeology in Piedmont, not only for researchers but also to provide support to local authorities and professionals working on groundwater management.
