Thetis collaborated for the design and construction supervisor of the activities concerning the continuation of the morphological restoration of the intertidal surfaces. The intertidal surfaces considered are located in the Northern sector of the lagoon and reached by the Cenesa channel and its branches, Siletto channel and Lanzoni channel, which sorround the Lanzoni valley and which once conveyed the Sile and Piave waters.

The morphological structures covered by the executive project of the 2nd phase – 1st lot are the Crosera Siletto salt marsh and the Siletto one both located on the South shore of the Siletto channel.

In particular:

  • • Crosera Siletto salt marsh spread over a perimeter approximately equal to 888 m, with an area of nearly 29.760 m2 and a total capacity (considering an backflow rate between +40 cm and +70 cm a.s.l.) of 48.272 m3.
  • L• Siletto salt mersh spread over a perimeter approximately equal to 738 m, with an area of nearly 20.050 m2 and a total capacity (considering an backflow rate between +60 cm and +70 cm a.s.l.) of 33.000 m3.

Finally, the project involves the construction of the maintenance dredging of the refuge port of Lido Treporti located on the sea side, for a total volume of approximately 135.000 m3, of which about 81.300 m3 to be transferred to the two salt marshes of Crosera Siletto and Siletto.
