Landslides are a serious concern in the Western and Eastern Ghats of India. They impede the social and economic development of the region. Landslides can manifest in various forms like translational slides, rock falls, debris flow, etc. Each type of landslide has a set of characteristic conditioning factors and are required to be modelled separately. This study attempts to develop an integrated model to assess different types of landslides in a region. A stretch of hill road severely affected by different of types of landslides along the Kodaikkanal–Palani traffic corridor is selected for the study. The model developed is capable of assessing the susceptibility of the region to translational slides, rock falls and debris flow. Analytical Network Process, a heuristic model that can accommodate the interdependency of the conditioning factors is used to model landslide susceptibility. The results of the study show that the model performs satisfactorily. Control measures are also suggested for mitigating landslides in the region.

山体滑坡是印度西部和东部高止山脉的一个严重问题。它们阻碍了该地区的社会和经济发展。滑坡可以表现为多种形式，如平移滑坡、岩崩、泥石流等。每种类型的滑坡都有一组特征调节因素，需要单独建模。本研究试图开发一个综合模型来评估一个地区不同类型的滑坡。本研究选择了沿 Kodaikkanal-Palani 交通走廊受不同类型滑坡严重影响的一段山路。开发的模型能够评估该地区对平移滑坡、岩崩和泥石流的敏感性。分析网络过程，可以适应条件因素相互依赖性的启发式模型用于模拟滑坡敏感性。研究结果表明，该模型的性能令人满意。还建议采取控制措施以减轻该地区的山体滑坡。
