The use of cartographic modeling to assess the impacts of coastal flooding: a case study of Port Said Governorate, Egypt

Low-set coastal areas are expected to aggravate inundation on account of sea level rise (SLR). The present study is planned to appraise the impacts of coastal flooding. in Port Said city, Egypt by using remote sensing,GIS, and cartographic modeling techniques. To accomplish this scope, Landsat 8-OLI image dated 2016 and SRTM 1Arc-Second Digital Elevation Model (DEM) data were used.Landsat imagewas classified into seven land use and land cover (LULC) classes by using remote sensing and GIS’s software. Different inundation scenarios 1.0, 2.0 and 3.0-m coastal elevation were used to figure the influence of SLR on the study area. Estimation of potential losses under SLR was made by overlaying the expected scenarios on land use. The inundation areas under the expected SLR scenarios of 1.0, 2.0, and 3.0 m were estimated at 827.49, 1072.67, and 1179.41 km2, respectively. In conclusion, this study  demonstratedthat expected coastal flooding scenarios will lead up to serious impacts on LULC classes and coastal features in the study area.
