ABSTRACT
The present study is conducted in investigate the patterns of wave propagation and
transformation in the Eastern Harbor, and to predict the wave heights inside it using
CGWAVE model and also to estimate wave run up and overtopping at its surrounding
seawall using ACES software package. The investigation showed that, during NW storm
relatively rough wave conditions (wave heights of about 2 m) were predicted in the eastern
and northeastern parts of the harbor. During NNE storm the rough conditions were
predicted to affect most parts of the Eastern Harbor. Estimations of wave run up and
overtopping at the seawall in the area off the coastline to the east of El-Mansheya using
ACES software Package gave a run up value of 3.23 m with an overtopping rate of about
100 liters/s-m. The model results show good agreement with observations. The incident
wave height (1.75 m) used in these calculations is that predicted by CGWAVE at depth
contour of 2.5 m during NNE storm wave with Hs0 of 3.4 m and Ts of 9.0s
