Abstract This study was conducted to investigate the spatiotemporal changes of land use/land cover (LULC) along the eastern coast of the United Arab Emirates (UAE) over a 20-year period using an integration of remote sensing and Geographic Information Systems techniques. The impact of land use change on flooding potential was also investigated through hydrologic model simulations. Landsat images of the years 1996, 2006 and 2016 were processed and analyzed. Change detection was carried out to assess changes in the built-up areas. Furthermore, the impact of urbanization on flooding was assessed using a hydrologic model in two major watersheds of Fujairah Emirate. It was observed that for the period 1996–2006 the vegetation and the built-up areas had increased at a rate of 11.23% and 24.56%, respectively. For the period 2006–2016, this expansion more than doubled in terms of the vegetation class (27.51%) and slightly increased for the built-up class (28.98%). The change detection analysis revealed that urbanization has mostly occurred along the coastal boundary. Hydrologic model simulations quantified the role of urbanization in increasing the flooding potential. The increase depends on watershed characteristics and the rate of change in urbanization and the magnitude of the rainfall event.

阿联酋东海岸的土地利用/土地覆盖变化及其对洪水风险的影响

摘要 本研究旨在利用遥感和地理信息系统技术的结合,调查阿拉伯联合酋长国 (UAE) 东海岸 20 年间土地利用/土地覆盖 (LULC) 的时空变化。还通过水文模型模拟研究了土地利用变化对洪水潜力的影响。处理和分析了 1996、2006 和 2016 年的 Landsat 图像。进行了变化检测以评估建成区的变化。此外,使用富查伊拉酋长国两个主要流域的水文模型评估了城市化对洪水的影响。据观察,1996-2006 年期间,植被和建成区分别以 11.23% 和 24.56% 的速度增加。2006-2016 年期间,这种扩张在植被类(27.51%)方面增加了一倍多,在建成类(28.98%)方面略有增加。变化检测分析表明,城市化主要发生在沿海边界。水文模型模拟量化了城市化在增加洪水潜力方面的作用。增加取决于流域特征和城市化的变化率以及降雨事件的强度。
