Abstract
The lagoon of Venice is located on the easte rn side of the Po plain. It is abo ut 55 km long and 13 km wide. Th e delta systems of Po , Adige and Brenta rivers limit the lagoon to the south, whilst Sile and Piave rivers to the north. The lagoon is closed by two barrier islands: Lido and Pelle strina. Inside th e lagoon several typical forms of this peculiar environment can be seen: isles, channels, salt marshe s, tid al flats, fluvial deltas and also man made forms as landfills (casse di colma ta). In the fieldtrip the basin behin d the Pellestrina barri er island is visited . Here Brenta has bee n the dominating river sweeping thi s territory with a lot of br anches as can be shown by geological and geomorp hological evidences along with archaeo logica l and historical da ta. In the island of Pellestrina the coastal defen ces built up by Veneti ans are found . Here few years ago a huge renourishment has been made to enlarge the beach. Inside the lagoo n a morphological int eresting element are the landfills of Porto Marghera , which alte red the normal flood of the tides but in one case Ofdindu strial zone) became oasis of natural interest
