IV. Retreating Shorelines
273
The Lido di Ostia is one of the important resorts for Romans going on a shore
holiday. Here coastal erosion has considerably reduced the beach area. A
feasibility study conducted by N.V. HAECON, a Belgian company, recommended
the monitoring of the dredging carried out on the nearby coastal zone, and a
beach nourishment scheme which includes the use of 2.6 million m3 (3.4 million
cu.yd) of sand. In its Progetto Litorale '83 study, the city of Rome drew-up plans
for new developments along the "Roman beach area". The plans consider the
establishment of a marina at Isola Sacra. Material removed there, and additional
sand from marine sources, could be used for a beach nourishment scheme to
restore the damaged Fiumicino beaches.
3.3.3 Ostend, Belgium
True, the soft approach may not be applicable in all instances. A particular case
that comes to mind is Ostend, Belgium's most famous coastal resort. Construction
of a fort (Fort Napol6on), at the turn of the century, has seriously disturbed, ever
since, normal sand transport. Building of groins did not solve the problem.
Strong erosion, often the consequence of storm waves caused by refractioninduced wave energy concentration, is endangering beach, dike, and structures
beyond it.
Beach nourishment alone is not suited because Ostend is also a cross-channel
port, and the navigation channel must be kept open. Big scale beach nourishment
would extend beach slopes too far seawards. Yet, the toe of the boardwalk-dike is
presently almost unprotected against sapping by the sea ; were it to collapse, it
would entrain the weakening of the dike's buildings foundations. Recent storms
have evidenced the urgency of adequate protection measures as even boardwalk
pavement was uprooted by their fusy (1994, 1995).
