Mori–Torbole tunnel

[2] The tunnel reduces the risk of flooding in Verona and environs from once every seventy years to once every two centuries.

When the tunnel is open, the temperature shock and inflow of mud caused by the sudden influx of the Adige's water endanger the lake's fish populations, although the lake's larger volume is able to absorb large quantities of extraneous water into itself.

Using an idea already established in the 18th century, Venice's Water Magistrate proposed constructing a diversion tunnel to Lake Garda that would alleviate flooding by conveying that part of the Adige's flow exceeding the river's carrying capacity.

The most appropriate solution was considered to be a tunnel originating on the right bank of the Adige near Ravazzone (a subdivision of Mori) and terminating at Lake Garda to the south of Torbole.

The depth of the lake at that location would allow solid material that might be transported by the water to be deposited without damage.
