WP3 – Act. 3.2: Testing some provisions of the ICZM
Protocol through local/regional demonstration projects
The implementation of the Article 8 of the ICZM Protocol
in the Puglia Region: proposal for the individuation of
the set-back zone in the pilot area of Torre Guaceto and
neighboring costal area of Brindisi.
ARPA Puglia – Regione Puglia
Technical meeting with PAP/RAC NFPs
Rimini, 24 September 2013
The Pilot Project area is characterized by the high heterogeneity of the
coastal geomorphology and habitats as well as by different uses of the
territory, pressures and management regimes (protected zones,
touristic, urbanised and industrial ones).
Due to the above mentioned
characteristics,
the
pilot
area can be considered a
good test zone for the
implementation of the Art. 8
of the ICZM Protocol.
Technical meeting with PAP/RAC NFPs
Rimini, 24 September 2013
The set-back zone in the pilot area was estimated following two
different steps:
1) Estimation of the set-back zone baseline, intended as “the
highest winter waterline”;
2) Drawing of the set-back zone, simply created as a 100 meters
buffer of the same baseline in the first approximation. The setback zone was further adjusted widening the strip where
opportune (according with its role in biodiversity protection,
ecosystem maintenance and coastal adaptation to climate change
and the hydraulic risk) or narrowing according to the “adaptation
clause” (Article 8-2b).
Technical meeting with PAP/RAC NFPs
Rimini, 24 September 2013
The set-back zone baseline was estimated based on the integration
of results from four different methods/approaches:
1) Empirical estimation of run-up level by means of visual check in the
coastal belt. Based on the inspections on the coastal belt after the storm
surges and the positioning (by GPS) of the heavy materials transported by
the waves (large pebbles and relatively large and heavy tree trunks);
2) Empirical estimation of run-up level and flooding in the coastal area by
means of vegetational aspects. Based on the presence/absence of the
pioneer and/or structured coastal vegetation species;
3) Run-up estimation by mathematical model. This approach provided the
estimation of the maximum sea level rise on the coast due to the
simultaneous occurrence of the phenomena of wave set-up, wave run-up,
wind set-up and tides;
4) Maximum Flooding (Tsunami impact) estimation by mathematical model.
Based on the morphological features of the seabed and coastal areas,
adapting hydrodynamic formulas and relevant mathematical models for the
estimate of the extent of extreme flooding and risk along the coast.

All the results from the four methods have been mapped dividing the
coastline in stretches (the example of the stretch 6-7 in the figure).
Technical meeting with PAP/RAC NFPs
Rimini, 24 September 2013
The “integrated” set-back baseline was used to draw the set-back zone
for each coastal stretch (the example of the stretch 6-7 in the figure).
Technical meeting with PAP/RAC NFPs
Rimini, 24 September 2013
Moreover, for each coastal stretch the information on land uses and
criticalities according to the proposed set-back zone have been reported
(results from the pilot project activities).
