A landslide is the movement of rock, debris or earth down along the slope under the gravity. It may cause to loss of people’s life and their private and public properties. Landslide is a common hazard in steep slope areas, especially during the rainy season. A study of landslide helps urban planners, engineers and local communities to reduce losses caused by existing and future landslides by means of prevention, mitigation and avoidance. Therefore, the prime aim of this paper is to produce acceptable landslide hazard map for Chenab valley, Jammu and Kashmir. Semiautomatic extraction of the landslide is a suitable method that has been used in this paper to extract the location and extent of the landslides. IRS LISS-IV and CartoDEM have been used for object-based image analysis to extract and prepare a landslide inventory map. About 84 landslide potential sites have been identified by the semiautomatic extraction approach. Landslide numerical risk factor model is derived by using thirteen thematic layers with landslide inventory to prepare the landslide hazard map. The result showed that 21% area of the Chenab valley is falling under the very high hazard zone category of the landslide. The final result of the investigation will definitely be useful in the decision-making procedure at the time of emergency and will be used to prepare a preparedness plan for high-risk areas of Chenab valley. The ROC curve method is used for accuracy assessment that signifies the acceptable result for landslide susceptibility zonation of Chenab valley with 0.956 AUC value.

使用滑坡数值风险因子模型和通过 OBIA 在查谟和克什米尔(印度)的 Chenab 谷编制的滑坡清单的滑坡敏感性绘图

滑坡是岩石、碎屑或泥土在重力作用下沿斜坡向下移动。它可能导致人们的生命及其私人和公共财产的损失。山体滑坡是陡坡地区的常见危害,尤其是在雨季。滑坡研究有助于城市规划者、工程师和当地社区通过预防、缓解和避免的方式减少现有和未来滑坡造成的损失。因此,本文的主要目的是为 Chenab 山谷、查谟和克什米尔制作可接受的滑坡灾害地图。滑坡的半自动提取是本文用于提取滑坡位置和范围的合适方法。IRS LISS-IV 和 CartoDEM 已被用于基于对象的图像分析,以提取和准备滑坡清单图。通过半自动提取方法已经确定了大约 84 个滑坡潜在地点。滑坡数值风险因子模型是通过使用带有滑坡清单的 13 个专题图层来准备滑坡危险图而推导出来的。结果表明,Chenab 山谷 21% 的区域属于滑坡的非常高危险区类别。调查的最终结果肯定会对紧急情况下的决策程序有用,并将用于为 Chenab 山谷的高风险地区制定准备计划。ROC曲线方法用于精度评估,表明Chenab山谷滑坡敏感性分区的可接受结果,AUC值为0.956。滑坡数值风险因子模型是通过使用带有滑坡清单的 13 个专题图层来准备滑坡危险图而推导出来的。结果表明,Chenab 山谷 21% 的区域属于滑坡的非常高危险区类别。调查的最终结果肯定会对紧急情况下的决策程序有用,并将用于为 Chenab 山谷的高风险地区制定准备计划。ROC曲线方法用于精度评估,表明Chenab山谷滑坡敏感性分区的可接受结果,AUC值为0.956。滑坡数值风险因子模型是通过使用带有滑坡清单的 13 个专题图层来准备滑坡危险图而推导出来的。结果表明,Chenab 山谷 21% 的区域属于滑坡的非常高危险区类别。调查的最终结果肯定会对紧急情况下的决策程序有用,并将用于为 Chenab 山谷的高风险地区制定准备计划。ROC曲线方法用于精度评估,表明Chenab山谷滑坡敏感性分区的可接受结果,AUC值为0.956。结果表明,Chenab 山谷 21% 的区域属于滑坡的非常高危险区类别。调查的最终结果肯定会对紧急情况下的决策程序有用,并将用于为 Chenab 山谷的高风险地区制定准备计划。ROC曲线方法用于精度评估,表明Chenab山谷滑坡敏感性分区的可接受结果,AUC值为0.956。结果表明,Chenab 山谷 21% 的区域属于滑坡的非常高危险区类别。调查的最终结果肯定会对紧急情况下的决策程序有用,并将用于为 Chenab 山谷的高风险地区制定准备计划。ROC曲线方法用于精度评估,表明Chenab山谷滑坡敏感性分区的可接受结果,AUC值为0.956。
