Recent hydrogeological and geophysical surveys provide documentary evidence that saltwater intrusion may extend inshore up to 20 km away from the Adriatic coastline with the contaminant plume from near ground surface down to 100 in depth in some areas. The actual salt distribution is the outcome of a number of factors, including the ground elevation markedly below the mean sea level (down to -4 m locally), the seawater encroachment along the final 10-15 km of the regional watercourses (Brenta, Bacchiglione, Adige, Gorzone), and the drainage practices implemented in the reclaimed area. The fresh-salt water interface is generally between 2 and 30 in deep and exhibits a pronounced seasonal variation. At the same time an ongoing settlement due to peat oxidation promoted by fanning activities is observed in most of the area south of the Venice Lagoon that was reclaimed from 1892 to 1967 and is rich in organic matter. Overall land subsidence over the last 70 years ranges between 1.5-2 m and is still in progress at a rate of 1.5-2 cm/y. As a major result a large fraction of the reclaimed land lies below the mean sea level with an increasing exposure to flooding during severe winter storms and saltwater intrusion from the Adriatic Sea, the nearby Venice Lagoon, and the river beds that locally lie above the surrounding ground surface. To mitigate both hazards the implementation of a drainage strategy of the reclaimed area intended to maintain the water table as high as possible would be required. This could decelerate the peat oxidation (hence the related land subsidence) and oppose the inland subsurface salt convection and dispersion. Moreover the design of mobile gates at a few river mouths (e.g. the Brenta river) could create an effective barrier against the seawater migration upstream the watercourses in the hottest and driest summers."@en . @prefix istituto: . prodotto:ID93869 prodottidellaricerca:prodottoDi istituto:CDS080 . @prefix unitaDiPersonaleInterno: . prodotto:ID93869 pubblicazioni:autoreCNR unitaDiPersonaleInterno:MATRICOLA5178 , unitaDiPersonaleInterno:MATRICOLA3743 , unitaDiPersonaleInterno:MATRICOLA9617 . @prefix parolechiave: . prodotto:ID93869 parolechiave:insiemeDiParoleChiave . istituto:CDS080 prodottidellaricerca:prodotto prodotto:ID93869 . unitaDiPersonaleInterno:MATRICOLA5178 pubblicazioni:autoreCNRDi prodotto:ID93869 . unitaDiPersonaleInterno:MATRICOLA3743 pubblicazioni:autoreCNRDi prodotto:ID93869 . unitaDiPersonaleInterno:MATRICOLA9617 pubblicazioni:autoreCNRDi prodotto:ID93869 . ns7:ID99649 pubblicazioni:rivistaDi prodotto:ID93869 . parolechiave:insiemeDiParoleChiaveDi prodotto:ID93869 .
