description Sea Level Rise (SLR) is a vital outcome of the environmental global warming phenomenon. This paper aims to investigate the basic properties of tides in Alexandria, Egypt and to analyze Sea Level Rise (SLR) in Egypt over a long period in order to examine the differences in Egypt's vertical geodetic datum. The annual relative SLR at Alexandria between 1906 and 2020 was found to be 2.6 mm/year. Moreover, the relative SLR has been 3.1 mm/y for the last two decades, 2001-2020. It could be considered the most appropriate value to be taken into consideration in the Egypt's coastal management activities. Carrying out additional investigations is suggested to investigate the major variations of MSL in Egypt at other TG sites over both the Mediterranean and Red seas. Based on an available data and accomplished results, it is recommended to regard the Egypt's MSL datum as a semi-kinematic rather than a fixed one.
