Shoreline Changes in Front of New Mansoura City

The shoreline changes of the coastal zone at New Mansoura City which extends about 27km, have been studied using GIS technique based on RS data. The shoreline spatial and temporal changes in the interval time between years;1984 and 2018 has been estimated. The results show that the coast of New Mansoura City has been affected by morphological changes due to the shoreline accretion and erosion. The area has been subjected to increase in the accretion areas by nearly 2.34 km2, however, the erosional areas reach about 0.195 km2.The average rate of the shoreline accretion area was around 3.12 m/y, while the rate of the shoreline erosion area was -1.23m/y. Accordingly, the shoreline in the study area is mostly an accretion shoreline and the erosion areas are very limited and should be protected.
