EXPERIMENTAL STUDY OF THE HYDRAULIC BEHAVIOUR OF GROYNE SYSTEMS

Julio Patriarca Barcelo

Abstract


Results of an experimental study of the hydraulic behaviour f groyne systems, a very widespread coast erosion protection structure,are described. The characteristics of the evolution of beach stretches between groynes under the action of waves with different obliquity,heights and periods are defined. The results obtained are intended for design of systems of functional groynes which secure an adequate partition of the beach in satisfactory hydraulic conditions, and also meeting use requirements, notably from the architectural and recreation standpoints. Additionally the author briefly discusses longsh-ore drift and presents some experimental conclusions on the relations between longshore drift and the characteristics of the waves.
