Abstract
The aim of this project is to single out sections along the final tract of the river
Tiber, from the Castel Giubileo breakwater to the estuary, including main
feeders, in need of flood defence management interventions and environmental
redevelopment. After running through the city of Rome, the Tiber flows
downstream through a territory where urban needs coexist with cultural heritage
and a particularly riparian ecosystem. For this project it was therefore decided to
use bioengineering techniques in order to bring about the minimum impact on
both the environment and the landscape. These can be used to minimise
streambank erosion, to prevent flood events and for streambed shaping.
Furthermore, they are a valid tool for the restoration of the ecological integrity of
the riparian ecosystems and wetlands. The next step was to pinpoint critical
zones in need of a new embankment system for the security of Rome’s suburban
districts nearby. The final product was the development of a cartographic support
of the study area, elaborated with GIS software \“Arc Gis 9.1”, listing all the
planned works by area as well as the most suitable techniques in accordance with
the entity of the problem and the constraints of that zone. In addition, we drew
up a technical data sheet for each kind of intervention, pinpointing all the
locations along the Tiber where each intervention is planned. The shapefiles and
technical data sheets are useful instruments for the requalification of what
remains one of the most beautiful and vulnerable sections of the river Tiber.
Keywords: flood defence, bioengineering techniques, vegetated rock wall, coir
fiber roll, flood retention basin, sill, rehabilitation of natural habitats.
