Detached breakwater systems used to enlarge and protect extensive stretches of coastline can be designed with various methodologies. The latter may differ greatly from one another; some mainly have the geometric parameters and characteristic of the formation to be obtained and do not take the site's sedimentary variables into consideration. Designing and constructing these structures face a great problem in the lack of knowledge as to the coastline's morphology in its final condition when the situation of equilibrium is reached. Different alterations carried out afterwards on these structures to obtain the initially preset results are extremely costly. This study will reveal that, beyond ratios between dimensions and extreme climate variables, the siting and geometry of breakwaters forming the system will be directly affected by the variables that littoral dynamics and sedimentation may determine. This position must not be too far or too near since it may restrict the availability of sediments and therefore affect the formation considered. It will be deemed that, for an optimum design of these structures, the distance between detached breakwaters forming the system will be established on the basis of sustainability and with respect to water circulation an renews of the protected aera.
