Yanbu is the second largest port and population settlement on the Saudi Arabian Red Sea coast. With the increasing development of its nearby coast, the geomorphological characteristics of the region must be studied in detail in order to inform future developments of the region. This study examines the region’s suitability for future development. A high-resolution map of the coastal area under study was drawn by analysing Shuttle Radar Topography Mission-Digital Elevation Model (SRTM-DEM) data and Advanced Spaceborne Thermal Emission and Reflection Radiometer-Digital Elevation Model (ASTER-DEM) data, using remote sensing images from Landsat satellites. Landsat ETM+ images taken in 2000 and 2015, alongside remote sensing analyses, field observations, and geological mapping, were used to describe the geomorphological and topographical characteristics of the Yanbu coast. Both principal component analysis (PCA) and false colour composite (FCC) were the most effective remote sensing techniques for mapping the geomorphological characteristics of the coastal plain. The true colour of the combination bands 3, 2, and 1 was the best at showing the areas and features of coral reefs. Thus, the main geomorphological units in the study area were identified, including wadi systems, dunes, alluvial fans and fan deltas, fluvial terraces, sabkhas, coral reefs, platform reefs, islands, sharms, and sea heads.

使用遥感技术解释沙特阿拉伯延布市红海东海岸的地貌特征

盐埠是沙特阿拉伯红海沿岸的第二大港口和人口居住区。随着附近海岸的不断发展，必须详细研究该地区的地貌特征，以便为该地区的未来发展提供信息。这项研究考察了该地区未来发展的适宜性。通过分析航天飞机雷达地形任务-数字高程模型（SRTM-DEM）数据和先进的星载热发射和反射辐射计-数字高程模型（ASTER-DEM）数据，绘制了正在研究的沿海地区的高分辨率地图。从Landsat卫星感应图像。在2000年和2015年拍摄的Landsat ETM +图像，以及遥感分析，实地观察和地质制图，用来描述盐埠海岸的地貌和地形特征。主成分分析（PCA）和假彩色合成（FCC）都是绘制沿海平原地貌特征最有效的遥感技术。组合带3、2和1的真实颜色最能显示珊瑚礁的面积和特征。因此，确定了研究区域的主要地貌单位，包括旱谷系统，沙丘，冲积扇和扇三角洲，河流阶地，sabkhas，珊瑚礁，平台礁，岛屿，sharm和海头。组合带3、2和1的真实颜色最能显示珊瑚礁的面积和特征。因此，确定了研究区域的主要地貌单位，包括旱谷系统，沙丘，冲积扇和扇三角洲，河流阶地，sabkhas，珊瑚礁，平台礁，岛屿，sharm和海头。组合带3、2和1的真实颜色最能显示珊瑚礁的面积和特征。因此，确定了研究区域的主要地貌单位，包括旱谷系统，沙丘，冲积扇和扇三角洲，河流阶地，sabkhas，珊瑚礁，平台礁，岛屿，sharm和海头。
