1. Coastal erosion and sea level rise
Italy
About 1600 km (42%) of the low or delta coastlines, including
42% of Italian beaches, are already under erosion. Most of the
Italian coastal environment suffers from intense and growing
urbanization, tourism and industry pressure. The highest
erosion rates affect the major Italian river deltas, where 10
m/year retreat can be frequently observed (the Arno, Obrone,
Volturno and Po rivers)

2. Coastal Erosion
Coastal erosion has some very serious consequences, such as the destruction of
natural defenses, which cause the loss of economically important areas.
There are many reasons why coastlines are retreating:
❖ The gradual caving in or sinking of an area of land (SUBSIDENCE)
❖ Sea level rise
❖ The urbanization of the coasts
❖ The sediments transported by rivers are drastically decreasing

5. The Rising Level of the Sea in Italy
Only a few long sea level
records spanning to the
beginning of the 1900s
exist in the Mediterranean
Sea and these are located
at the northern coasts of
the western Mediterranean
(Marseille and Genoa) and
at the northern coasts of
the Adriatic Sea (Trieste
and Venice)
The sea level trends for the
three longer stations are
presently in the range 1.1 -
1.3 mm/yr, thus lower than
the estimated global value
for sea level rise.

6. The increasing frequency of floods in
Venice is connected to the rising
level of the sea, and to the heavy
rains, which are caused by the hot
atmosphere, which is able to hold
back humidity.
