The beach evolving in the Mamaia sea area represents a recent
geological deposit, which was built mainly from the
contribution of north-south oriented long shore terrigenous
sediments, but also from biogenic sediments, which have been
transported towards the beach, mostly through the shore
transverse transport (onshore-offshore). Between 1977 and
1987, several project proposals for the protection of the
entire touristic Mamaia beach were analyzed. Several
different concepts were presented, due to the fact that each
interpretation had to start with the new data on the erosion
state and each solution readjustment added new dimensions to
the construction site and also to the required financial
investments. Eventually, the decision was to start with a
series of processes which involved longitudinal-type
protection works, known to offer great efficiency on the
dissipation of the energy flux propagated with each wave,
and also the dam-chain type which is parallel to the shore.
At the end of 1988, following some severe storms, the
processes for the Mamaia resort coastal protection were
initiated under a state of urgency. These measures
represented the fourth draft developed over a period of ten
years and demanded the build of six longitudinal dikes out
of the nine required by the initially presented protection
