Resumo(s)
The coastal stretch of Boca do Rio, western Algarve, Portugal, is experiencing shoreline
retreat. Roman ruins are located along the beach section of the coast, and a 17th-century
fort is positioned over the cliff section. Both historic monuments are being destroyed by
erosion but need to be protected due to their heritage status. Aerial photograph analysis
was used to define the evolution of the coast for the period 1945–2001. Shoreline retreat
of 0.3 m/year was measured for the sandy coast and 14 mass movements in the cliff face
were identified. Considering the rate and style of shoreline evolution, several types of
management scenario were evaluated, with the favored measures being the removal of
the Roman ruins to a museum and the relocation of the fort inland.
