Geomorphic hazard and intense rainfall: the case study of the Recco Stream Catchment (Eastern Liguria, Italy)
A critical pluviometric event occurred in the
central-eastern Ligurian Riviera, 15 km from Genoa, on
1 June 2007. This event caused landslides and hydraulic
problems between Sori and Camogli and in the inland area
of the Recco Valley.
An analysis of the heavy rainfall was conducted.
Hourly precipitation data revealed a critical event between
04:00 a.m. and 07:00 a.m. local time, with more than
220mm of precipitation over three hours.
Slope movements were mainly debris flows that detached
from the lateral valleys of the Recco Stream catchment and
from well-maintained, wooded slopes that were also characterised
by cultivated terraces.
Numerous slide planes corresponded to the interface between
the surface cover and the underlying bedrock, which
presents an unfavourable geologic structure in terms of stability
assessment.
In most cases, the displaced material had a limited thickness.
Debris cover was rapidly channelled along small valleys,
which controlled the critical hydraulic conditions in the
secondary drainage network.
Man-made drainage systems were partially or totally
blocked in a very short time and, like the natural watercourses,
accumulated thick and extensive alluvial fans.
Most of the instability phenomena occurred in areas that
had been designated medium or low-risk areas during land
planning, and in sectors that were defined as stable, because
they lacked geomorphic indicators connected to landslide
risks.
The above considerations highlight some gaps of the
Recco Stream Master Plan. Therefore, to update this land
planning tool, it is necessary to extensively investigate local
geomorphological characteristics and to adopt a different
method for assigning weights to the geohazard maps
