The Tidal Range And The Observed Sea Level Variations At Alexandria Harbour

Abstract

On the basis of sea level observations of five years period (1975-1979), the basic properties of the tidal range at Alexandria are described. The problem of the combined effect of tides and meteorological factors on sea level is discussed. A more detailed description of this phenomenon is given by determining the frequency distributions of the tidal sea level range and also, by comparing the theoretical and the recorded range of tide during Spring and Neap tides. Finally, the mathematical relations between the greatest tidal range, the most pronounced sea level range and the average range are deduced.
