Abstract
         In the recent and coming decades, the climate change induced sea level rise (SLR), is considered a big challenge facing many countries especially coastal cities, islands, and deltas. The sea level rise has significant impacts on coastal systems included flood risks, coastal erosion, loss of coastal infrastructure, and danger of saltwater intrusion. This research aims to establish and observe the sea level fluctuation along the Mediterranean coast of Egypt. Two tide gauge stations were installed (Alexandria city and Port said city), to record the sea level each 30 minutes since 2010 till now. Acquiring and analysing the long-term datasets of the tide gauges were conducted in order to estimate the relative trend of sea level rise. A group of relationships of the sea level fluctuation on the basis of daily, monthly, and yearly, were produced. It can be concluded that the sea level rise within the period (2010 – 2020) was ranging from 2 to 5 mm/year, while the sea level was fluctuated from 65 mm to 650 mm.  The obtained results were compared and matched with other study covered the period from year 1943 to year 2000.
