Venice: A Fragile Destination

Flooding is one of the starkest environmental disasters which can wreck havocs in a nation. Venice, a beautiful destination for tourism might likely disappear if appropriate action and measures are not taken by the government to arrest the situations.
Venice is one of the world's island regions covered almost completely by water. The city of Venice is located within 118 minor islands that are linked with the bridges and separated by canals. The beauty of this situation is its artworks and architecture characterization that distinguish it. The flood tides that often threaten comes in from the Adriatic between autumn and the beginning of spring.
Venice has been experiencing flood disaster for a longtime. The renowned tourist region of Italy suffered a great deal from the effect of floods. Tourists had to attach plastic bags to their legs to take a dip in St. Mark's Square on Sunday when sea water rose beyond normal and gushed through the city. The water heights during the disaster extend to 1.49 meters that are about 5 feet. This goes beyond the normal range of the Adriatic Sea. The disaster was also accompanied by bad weather that took a toll on Italy during the weekend.


According to history, the recent acquaalta (Venice’s high water) is the sixth highest flood disaster since 1872. The flood took over the entire city and its peak reached several meters upwards. Many residents of the Italian city left the city mainland and relocated to other regions
Venice is under great threat of extreme storm waves and if careful measures are not taken to minimize the environmental disaster, it is likely that Venice might disappear. The proposed water level rise as a feature of international warming. On the expedition by the water level researcher, significant evidences were predicted that there is a fast change in the water. Research on regional systems like sediment compaction and anthropogenic processes revealed the concept of Vertical Ground Motion (VGM). This holds for the vital situations of Venice, and some other regions, which are specifically subjected to the present sea level surge. VGM is a significant issue for anthropisation of the seaside locations that are subjected to the current water level increase, which occurs at 2-3 mm/yr. typically, but, that spatially differs by numerous mm/yr.  VGM might help to understand their different reasons and contribute to the resolution of such a crucial social challenge. Recognizing the causes of VGM and anticipating their impacts is a probability, however, uncertainty continues to be large. In addition, anthropogenic causes, tectonics, mantle mechanics, volcanism, and glaciers modifications are amongst the major contributors in charge of upright ground motion. Anthropogenic reasons feature hydrocarbon or water pumping. Venice sediment deprivation is due to river diversion, dams and irrigation.

 There is need to take into consideration different factors because of their effect on the morphology, the function of structural task or volcanism is conceptually simple at energetic plate margins, although it is occasionally challenging to quantify. Mantle flow regularly forms the strong Earth by customizing the heterogeneous distribution of its interior masses. On the long-term, vibrant topography, i.e. the departure of the Earth's surface area from a static stability as a feedback to the viscous flow in the mantle, affects all components of the world with a magnitude that may go beyond 1000 m. As a remedial measure, the dike construction like Maldives can well fit in into Venice in order to control the action of flood.
