Hydrogeology of the Viverone Lake area (Piedmont, NW Italy)

The research regards the hydrogeological reconstruction of the left frontal sector of the Ivrea Morainic Amphiteatre (IMA). In detail the studied area includes the internal depression in which the Viverone Lake develops, the frontal morainic relief that borders the lake and the proximal sector of the external glaciofluvial plain. The local stratigraphy was reconstructed based on the interpretation of the water well logs. The surficial flow system flows generally from the morainic reliefs to the Viverone basin, feeding the lake. The intermediated aquifer feeds the lake, except at the lake floor (180 m a.s.l.) where the flow is directed from the lake towards the aquifer. The deep flow system is directed from the lake floor to East, while a westward flow is impeded by the presence of Complex D deposits. A drainage axis into the Complex A develops with NNW-SSE direction at the East of the Viverone Lake, from Roppolo to Alice Castello.
