For the estimation of erosion and _______________ accretion, the terrestrial satellite imagery was used, including multi-dates of MSS 1973, Landsat Thematic Mapper (TM) imagery of 1984, and ETM Keywords: 1990, 2001, and 2018. Two main methods were adopted; treatment and Shorelines; interpretation, in all the sites studied, with the exception of Rosetta. During Artificial concrete the period before the beginning of the construction of the Artificial Concrete breakwaters (ACBs); Breakwaters (ACBs), erosion increased but accretion decreased. However, Erosion rate; the exact contrary occurred after construction, where erosion decreased but Accretion rate. accretion increased.
