Morfologia plaż wybrzeży Wysp Zielonego Przylądka jako odzwierciedlenie ich litologii i warunków hydrodynamicznych

The authors presented the findings from the morphological and structural research of several beaches located on some of the Cape Verde Islands. These islands constructed from granulometrically and petrographically varied rocks, mostly origanated from Mesozoic and Tertiary volcanites. They are also influenced by tides: semidiurnal tides which reach a height of 0.5-1.5 m, and steady trade winds which blow from the north-east. It was revealed that the beaches in question in terms of their morphological and lithological features can be classified as environments characterised by considerable energy of coastal processes.
