Description
The complex interaction between morphogenetic processes acting on rocky coasts and substrate characteristics
difficult the assessment of its evolution at different time scales. In opposition to other coastal environments such
as beaches, where variations on substrate’s attributes are constrained to a few possibilities, rocky coasts expose
substrates having large amount of variables, among them, lithology, mechanical and chemical strength, density
and orientation of faults and joints and, rocks’ texture and structure (e.g., Trenhaile, 2003).
