Hazards from sea cliff instabilities are increasing because of the growing human occupation in coastal areas. Assessment of cliff hazards is very important in order to develop appropriate coastal management plans. In this study, a semi-quantitative heuristic method was developed to assess instability hazard for rocky coasts at Chabahar (Iran) along the northern coastline of the Gulf of Oman. In this method, seven factors affecting cliff instability, including: wave exposure, cliff height, cliff slope, rock resistance, lithology, bathymetry and beach width, were used to calculate an instability hazard index, from which a hazard map was constructed for the study area. Results were validated by statistical analysis of the previous instabilities detected by comparing old and new satellite images. According to the instability hazard class and cliff height, a hazard zone from the top of cliffs was determined within which development is not recommended.

伊朗Chabahar海岸管理的海崖不稳定危害评估

由于沿海地区人类的日益增多，海崖不稳定造成的危险正在增加。为了制定适当的海岸管理计划，对悬崖危险进行评估非常重要。在这项研究中，开发了一种半定量启发式方法来评估阿曼湾北部海岸线沿Chabahar（伊朗）的岩石海岸的不稳定危险。该方法采用了影响悬崖失稳的七个因素，包括波浪暴露，悬崖高度，悬崖坡度，岩石阻力，岩性，测深法和海滩宽度，以计算失稳危害指数，并由此构建了危害图进行研究。区。通过对旧卫星和新卫星图像进行比较，对先前发现的不稳定性进行统计分析，对结果进行了验证。
