Dataset used to infer regional slope stability , NW Himalaya
The study area concerning the data set is located between the 31˚36′1″ N, 78˚26′ 47″ E and 31˚27′10″ N, 77˚38′ 20″ E in Satluj River valley, NW Himalaya. This region has been subjected to spatio-temporal varying tectonic stress, owing to continent-continent collision orogeny, resulting in a diverse set of joints. This data is a part of a larger dataset that was compiled to infer the potential landslide damming in Satluj valley, NW Himalaya. The data set includes joint mapping data, values of input parameters that are used in the Finite Element Method based slope stability evaluation, and a table comprising all the landslide related details. Rock mass joint data (Supplementary Table 1) was collected in the field. Rock/soil samples, collected from each landslide, were analysed in the National Geotechnical Facility and Wadia Institute of Himalayan Geology, India. These values were used in models to evaluate slope stability of different types of landslides. Procedure described in the relevant Indian Standard (IS) codes was followed for the laboratory analyses. Such data set can be utilized to infer the pattern of rock mass joints in continent-continent collision orogeny on regional scale. At slope level, it can be inferred as a controlling parameter. The values of input parameters used in the FEM models (Supplementary Table 2) can be utilized as a reference for different types of rock mass and soil. Supplementary Table 3 comprises the following details related to the landslides; Type, Area, volume, Human population in the vicinity, Factor of safety, Total displacement, Morphological Obstruction Index, Hydro-morphological Dam Stability Index (HDSI).
