Short summary
We investigate the effects of digging a navigable canal on the hydrogeological system underlying a coastal lagoon. The research has been promoted by the Venice Water Authority, which is investigating different possibilities to avoid the passage of large cruise ships through the historic center of Venice, Italy. Numerical simulations supported by a proper hydrogeological characterization show that the exchange of water and contaminants from the subsurface and surface systems will be significant.
