Short summary

We have depicted the continental and marine surficial water–groundwater interactions in a large portion of the coastland encompassing the southern Venice lagoon and the northern Po river delta. The saltwater-fresh water transition zone is very irregularly-shaped and mainly depends on the morphologic setting and the subsoil architecture. An over-consolidated Pleistocene clay layer and buried Holocene sandy paleo-channels and paleo-ridge systems controlled the saltwater-fresh water exchanges.
