Popis: | This paper deals with the types, distribution and origin, of recent sand dunes in the coastal sector extending between El Burullus Lake and the Damietta Nile River branch, Egypt. Sand samples were studied for grain size distribution and mineralogical composition. It has been found that most of the dunes in the study area have been subjected to deterioration and removal due to the construction of summer resort buildings and making the international coastal highway. The remnant constitutes a belt of foredunes on the shore of Baltium extending westward to Burg El Burullus village. The dune’s origin is interpreted as the result of coastal drifting and the subsequent transport of the former Sebennitic Nile branch sediments eastward by the predominant longshore current and by Aeolian processes. The blown sand grains accumulated to form a belt of coastal sand dunes with longitudinal and crescentic forms. Urbanization of the coast has severely altered the landscape. Gaps and damaged dunes are included within the dune belt. The dune’s natural cycle of advance and retreat is upset and attains its destruction phase. The consequences of its destruction are numerous and lead to hazardous impacts on the shoreline, coastal building and the nearby international highway. |
