LONGSHORE CURRENTS AND WAVES AT BURULLUS COAST

[摘要] Littoral currents within the breaker zone and currents other than those induced by waves beyond the breaker zone exist with considerable magnitude along the Nile Delta coast. Analysis of the littoral currents within the breaker zone by four semi-empirical formulae involving energy, momentum and radiation stress principles indicates good correlation between predicted and observed velocities. Galvin-Eagleson approach gives the best fit. Current data are statistically analysed enabling the determination of the magnitude, direction and percentage of occurrence of any particular littoral current for any particular period. More comprehensive studies of the currents climate within the breaker zone and beyond the breaker zone for the entire Nile Delta coast covering a large number of years are under way,
