The International Geographical Union's Commission on coastal changes
examined during the 1972 to 1984 span the world's coasts. It evidenced the
important local effects of structural works and coastal land reclamation (e.g.
polderization) on sea levels, and warned of the indirect effects of the climatic
changes resulting from increased pollution and modifications in the global
atmosphere.
Harbor structures, for instance in Seal Cove (California), by causing shore
erosion, through their impact on the shoreline adjacent to them, are contributors
to slope failure.
Using his observations at South Bethany, DL, Westgate warned those who want
an unimpeded view of the sea, flattening dunes, and perching their buildings
close to the edge of the beach that "geologic evidence points to increasing
movement of the foredunes of the coastal beaches toward land, making additional
development so close to the water a risky business 14.
In Tunisia, harbor building at Tabarka disturbed natural sand accretion and
caused substantial transformations. A similar consequence resulted from portuary
works at Bizerte. Though no loss of beach space has been reported so far along
the Moroccan coast, removal of beach material for construction purposes between
Rabat and Casablanca may create future problems and new sources of sand and
gravel are sought for (personal communication with M. Bensaid, Int. Symp. of
Comm. World Geol. Map, Sub-Comm. on Appl. Geol., Trondheim, Norway, May
1986) 4 . The tourism development plans of the Moroccan coasts ought to give due
consideration to erosion potential along the Gibraltar Straits, particularly the
stretch from Tangiers to Ksar-es-Seghir. Other caution requiring areas include
the Fnidek to Tetouan region and the steep coast west of Oued Laou.
Off the coast of Lebanon and Israel, and too close to shore, dredging for
construction material led to severe beach territory loss. Efforts were made here
and elsewhere to counteract severe coastal erosion (fig. 7 and 8). Similar
situations arose on Brunei, and Indonesia is alarmed over intensive coastal
erosion.
