Аннотация:Geological and geomorphological location is reviewed for the seasideresortVaradero which is recreational area of international importance. The outlookon the natural scenario of this area evolution is of great concern. The analysis ofcoastal morpho- and lithodynamics is implemented. The interpretation of the term« coastal zone » is given along with the approach to the identification of its boundariesand components. The materials obtained formed the basis of a mathematical modelcharacterizing the lithodynamics component of the studied area evolution. Specificmeasures to preserve beaches from erosion by storm waves are proposed.
