The coast under study has been subdivided into 5 physiographical units. The physiographic area includes about 22 km of coastline, 10 of which of sandy beach, 5 of low rocky coast and 7 of cliffy coast. The outcropping rocks are those related to the Hercynian cycle, with the typical sequence of intrusive events represented by tonalites, granodiorites and leucogranitic plutons.
The studied area includes includes only the sectors B and C. The wave-cut (cliff) stretches of coast, oriented according to these lineations are considerably fractured and crossed by tectonic lines perpendicular to the coast, on which processes of linear erosion and deep valleys have evolved. All physiographical units under study present maximum exposure to the winds and waves from west and north-west. The morphology of the submerged beaches of north western Gallura is strongly affected by the outcropping of the crystalline basement that determines its geomorphological arrangement
The distribution of the dike set strongly affects coastal morphology by creating natural barriers to longitudinal transport, defining physiographic entities and creating tombolos and isolated rocks. La Liccia, Rena Majori and Bureddaggia are highly exposed beaches, liable to very intense swell with modest SW-NE net energy flow. Naracu Nieddu and Lu Litarroni beaches are poorly exposed, liable to intense swell with mild SW-NE net energy flow.
Tourism represents one of the predominant sectors of the local economic systems and has influenced all other forms of the use of those parts of coast and sea, who have oriented themselves towards an organisation suitable for the needs of tourism. Tourist activities include various compartments of quality of the agricultural nutrition sector (to think about wine, cheese, bread and so on) and furthermore traditional and artistic trade or craft (fabrication of baskets, carpets, ceramics, knives, leather, wooden objects etc.).
Of fundamental importance is the analysis of “progettualità” deriving from the socio-economic energies used for planning, programming (in particular of the local development programs, the instruments for urban development) and from those which regard actions in the area of the Quadro Comunitario di Sostegno also with the recent instrument of “Progettatione Integrata Territoriale” (PIT).
With these reports it will be possible to verify a new scheme of territorial order, which directly originates from knowledge about the intentions of the local administration and the economic world in relation to the two principal objectives of development:
