Abstract: | Although the western-Mediterranean coast of Egypt between Sallum and Alexandria, ~550 km long, has maintained a considerable
equilibrium throughout history, developers have built traditional protective structures in an effort to form sheltered recreational
beaches without taking into consideration its geomorphologic characteristics, coastal processes and their harmful impact on
the coastal environment and human safety. The improper practices in this environmentally valuable region have induced us to
undertake an initiative to carry out a morphodynamic analysis to provide a framework for understanding the relationship between
coastal morphology and the prevailing dynamic forces. Based on the degree of natural protection or wave sheltering, the study
shoreline can be categorized into four distinct morphotypical stretches: (1) high-energy wave-exposed shores and the outer
margins of the rocky headlands, (2) moderate to high wave-energy beaches along semi-exposed embayments and bays mostly downdrift
of the rocky headlands, (3) low-wave energy at semi-exposed headland lee-sided and pocket beaches, and (4) calm wave-sheltered
enclosing water basins for safe anchorages, moorings and recreation beaches. The results deducted will have practical applications
for shoreline management initiatives regarding sustained sites suitable for future beachfront development such as safe swimming
conditions, sport facilities, water intakes and sheltered areas for vessels. In addition, benefits realized by the understanding
of the morphodynamic processes would enhance our awareness of the significance of the role of western coast morphodynamics
in supporting sustainable development via shoreline management. As far as sustainability is concerned, the selection of appropriate
sites would help avoiding or minimizing the formation of the hard structures needed for creating safe recreation beaches.
On a national scale, results reached could provide reliable database for information that can be used in establishing a sustainable
shoreline management plan, which is, in turn, an essential part when implementing an Integrated Coastal Zone Management Plan
for this region of attraction. |
