The frequency distributions of the residual sea level along the Suez canal

Abstract EN

The residual sea level at five stations (Port Said, Kantra , Defersoir, Gineva and Port Tawfik) located along the Suez Canal are estimated by eliminating the predicted tide from the observed heights of sea level for two years 1984 and 1985.

The shapes and behaviors of the frequ ency distributions of the residual sea level are determined by calculating the first four moments (mean , variance.

skewne ss and kurto sis) for each month at the investigated stations.

The maximum residual height is observed at Port Tawfik .

where it varied between 130 and 150 ern eith er for positive or negativ e residuals .

The maximum positive residu al height at the other stations varied between 34 cm at Kantra and 70 cm at Defersoir, while the maximum negative ones changed between - 32 cm at Kantra and - 66 em at Defersoir.

At northern stations (Port Said and Kantra), the positive residual heights occur most frequently during the summer months, while the negative one are predominant during the winter months.

At the southern stations (Port Tawfik and Gineva) , the revers e is true .

Defersoir is considered as a transition region between the two regions .
