In the present authors attempted to have a clear insight into the
interworking of geotectonic, geomorphic, hydrologic and anthropogenic
factors leading to landslide in the Shiv khola Watershed, the most worst
affected region of Darjiling Himalaya. This book includes the parameters
responsible for landslide events in mountainous areas. It provides
knowledge and understanding to the local people, planners, and policy
makers about the causes and consequences of landslides as well as
provides a suitable method to mitigate the landslips. The book deals
with the role of land, water and soil in landslide phenomena. These
three attributes have been described in terms of critical rainfall,
critical slope, critical height and changes and development of drainage
network in landslides. Mitigations and site-specific management options
are evaluated considering the roles of local govt., community and other
organizations in both pre-slide and post-slide periods. Various
scientific methods have been used to assess the landslides that will
bring about tremendous help to researchers in the field. In particular,
Researchers in Mountain Geomorphology and Geological and Geographical
Society will get tremendous help from some topics such as 1-D slope
stability model, SCS Curve Number Technique, Assessment of morphological
parameters, application of RS & GIS, Application of Analytical Hierarchy
Process. Semi-quantitative approach is followed for understanding
spatial distribution of cohesion, friction angle slope, lithology and
lineaments, drainage, upslope contributing area, land use and land cover
types etc. This book also reveals some techniques and models for
initiating slope instability.
