Abstract
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.
