Sea level analysis using tide gauge observations at the northern delta coast, Egypt

The current study focuses on the analysis of observed sea level in northern delta coast, which is considered most important region Egypt. used sea-level data are records three tide gauge stations located north delta, Alexandria, Damietta, and Port Said. Different periods had been to be analyzed get astronomical surge heights. Geotide software obtain tidal harmonic constituents. cycle sort at locations gauges calculated results were as follows: a mixed semidiurnal type Alexandria Mean Sea Level (MSL), referred Egyptian Survey Authority datum (ESA-1906), calculated, datums each station International Terrestrial Reference Frame (ITRF-2014) else. Ten groups constituents obtained two them have largest amplitudes they M2 (Principal lunar), S2 solar). percentages surge, data, will shown section.
