ITALIAN EXPERIENCE ON SUBMERGED BARRIERS AS BEACH DEFENCE STRUCTURES

Abstract

The use of submerged barriers in Italy is rather new starting in the first 80's. Since that time more than 50 submerged barrier defence system were constructed and this type of structure is progressively complementing and substituting the traditional use of parallel emerging breakwaters. The paper presents documentation about the experience gained on the topic and describes and compares to prototype experience the design criterion suggested by the authors, based essentially on the selection of a proper wave attenuation necessary to obtain to desire profile modifications.
