Abstract
Portugal is one of many countries in the world to suffer from coastal erosion.
Conventional ways of protecting a coastline appear to entail some disadvantages.
An innovative and interesting way of protecting a local coastal zone by means of
multi-functional artificial reefs avoids some of them.
A multi-functional artificial reef (MFAR) is a submerged breakwater which
protects the local coastline and may also enhance the surfing possibilities and the
environmental value of the local area. The structure has several positive sideeffects:
first, it provides an unimpaired visual amenity; second, it offers tourist
and economic benefits by improving the surfing.
A 2D physical study is under way at LNEC to investigate the relations
between the breaker type and the submergence and the length of a MFAR. Two
different geometries were tested for different incident wave characteristics and
different water depths.
This paper presents the main characteristics of the physical experiments in
progress in a wave flume to analyze the influence of the submergence and the
length of a MFAR on the wave breaking type. The main preliminary conclusions
are that the length of the reef doesn’t have much influence on the breaker type
and that the shorter the slope of the reef the more the wave breaks towards the
crest.
