Abstract
This paper aims to underline the importance of monitoring studies during the
execution of activities, like beach nourishment using relict sands, that plan the
use of innovative technology. In fact, environmental monitoring studies allow
prompt intervention in the case of unexpected events or interference factors.
Potential negative repercussions on the marine environment could not be
estimated through characterization studies carried out ante operam. This paper
reports the monitoring study carried out for beach nourishment along the South
Latium coasts (Tyrrhenian sea). In this area Posidonia oceanica meadows are
present. In this context, a detailed and updated cartography and the knowledge of
the P. oceanica beds distribution (a \“priority habitat” in the UE Habitats
Directive) allowed prompt identification of potential effects on the seagrass
caused by specific technical procedures of the beach nourishment, not
well-known in the planning phase of the project.
Keywords: environmental monitoring, beach nourishment, Tyrrhenian sea.
1 Introduction
Among the different experimented technologies to control coastal erosion, beach
nourishment with relict sands is considered a useful method to protect beaches,
often preferable to the coastal defence structures (seawalls, groynes, emerged
breakwaters) [1–3].
Nowadays, marine sand deposits exploitation is a very common technology
both in Europe and in the rest of the world. The first documented beach
nourishment project took place in USA during 1922-1923 at Coney Island,
