AN ATTEMPT FOR SAND TRANSPORT BUDGETS BY WIND ALONG NORTHERN SINAI BEACHES, EGYPT ABDEL GALIL, M.*, HEREHER, M. E.* and EL-ETR, H. A.** * Environmental Science Dept., Faculty of Science at Damietta, Mansoura University ** National Authority for Remote Sensing and Space Sciences, Cairo The Mediterranean beaches of Sinai Peninsula extend for more than 200 km, from Port-Foad (in the west) to Rafah (in the east). The shoreline takes three main orientations: i) NW-SE, along the northwestern fringe; ii) fairly E-W, along the middle part; and iii) NE-SW, along the eastern fringe. The relation between the direction and duration of the dominant wind, and the orientation of the shoreline governs the net sand transport budgets, toward sea or toward land. Wind data revealed a big difference in both direction and magnitude along Northern Sinai beaches. The northwestern Sinai beaches are characterized by high-energy wind, whereas the other beaches posses lower energy winds. The whole beaches were sampled and the mean grain size was obtained for sand transport calculations. The transport budgets along the beach were calculated according to Kadib (1963) formula. The highest transport rate is recorded at the beach of El-Tina Plain, and the lowest at El-Arish beach. The present study showed that there are three types of beaches along Northern Sinai, in relation to sand transport budgets: 1-beaches of net sand transport toward the sea (El-Tina Plain and El-Telool), 2- beaches of net sand transport toward the land (Bir El-Abd and El-Arish), and 3- beaches of partial equilibrium between landward and seaward transports (Rafah).
