Gaza’ coastal zone suffers from permanent erosion as a result of the anthropogenic intervention. This study aims to assess and map land-use / land cover and shoreline changes in Gaza coastal zone using remote sensing and GIS tools as a step towards implementing coastal zone management. In addition, bathymetric map will be extracted using Landsat-8 image. Firstly, land-use / land cover change detection was carried out using SPOT-5, Landsat and Quick Bird for the years 2004, 2009 and 2016. Six classes were assigned to the study area using maximum supervised classification to investigate the evolution during past period. Secondly, change detection along the shoreline was implemented over the past 42 years from 1972 to 2014. Finally, the ratio transform technique was applied to the newly acquired multi-spectral image to extract the nearshore bathymetric map of the coastal area. Results of change detection revealed that coastal area was significantly changed: urban/built-up and agricultural area expanded, whereas area of bare land / sand shrank by 14,52 km². In addition, shoreline analysis showed that, northern regions were substantially eroded by 186,15,103 m² in the period 1998–2007. Moreover, an accretion occurred at the southern beach of Gaza's fishing port with a rate of 9,53,103 m²/year during the period 2007–2014. Ultimately, it is concluded that ratio transform algorithm used to extract bathymetry could retrieve depths from -25 m to -30 m. In addition, the result shows a good correlation between the estimated algorithm depths and the observed depths.

由于人为干预，加沙的沿海地区遭受了永久性侵蚀。这项研究旨在使用遥感和GIS工具评估和绘制加沙沿海地区的土地利用/土地覆盖以及海岸线变化，以此作为实施沿海地区管理的一步。另外，将使用Landsat-8图像提取测深图。首先，使用SPOT-5，Landsat和Quick Bird分别进行了2004、2009和2016年的土地利用/土地覆盖变化检测。使用最大监督分类将六个类别分配到研究区域，以调查过去时期的演变。 。其次，在1972年至2014年的过去42年中，实施了沿海岸线的变化检测。最后，将比率变换技术应用于新获取的多光谱图像，以提取沿海地区的近岸测深图。变化检测结果表明，沿海地区发生了显着变化：城市/建成区和农业面积扩大，而光秃秃的土地/沙地的面积缩小了14,52 km²。此外，海岸线分析显示，北部地区在1998-2007年期间受到186,15,103 m ^2的侵蚀。此外，在2007-2014年期间，加沙渔港南部海滩的吸积量为9,53,103 m ² /年。最终得出的结论是，用于提取测深的比率变换算法可以检索到-25 m至-30 m的深度。另外，结果表明估计的算法深度与观察到的深度之间具有良好的相关性。
