Variations of beach sands with seasons, beach slope and shore dynamics on the Nile Delta coast

Sandy beaches of the Nile Delta coast show a marked variation of grain size with the season and with the changing shore dynamics. Average median grain size of beach sands ranges from 1.98 0 in winter to 2.40 0 in summer. Beach face slope is shown to depend primarily on the median diameter and standa...

Tartalmi kivonat:Sandy beaches of the Nile Delta coast show a marked variation of grain size with the season and with the changing shore dynamics. Average median grain size of beach sands ranges from 1.98 0 in winter to 2.40 0 in summer. Beach face slope is shown to depend primarily on the median diameter and standard deviation of beach sediments. The highest correlation coefficient (0.908) is found between slope and median, and there is also a significant correlation (0.806) betwee nslope and sorting. Relying upon statistical analysis, it is demonstrated that the grain size of beach sands is proportional to the shore dynamics affecting Nile Delta coast. A procedure is suggested for the determination of diameter of sand grains about to be moved or added to the beach under a range of reasonable wave heights and current velocities.
