Landlside
Landslide
Landslides are downward and outward movement of slope materials such as rock debris and earth, under the influence of gravity.
Strategies for Landslide Risk Treatment
Landslide risk treatment is the ultimate objective of the risk management process which aims to mitigate the effects of the hazard. This encompasses a five-pronged strategy comprising:
i) Treating vulnerable slopes and existing hazardous landslides. ii) Restricting development in landslide-prone areas. iii) Preparing codes for excavation, construction and grading. iv) Protecting existing developments.
v) Monitoring and warning systems. vi) Putting in place arrangements for landslide insurance and compensation for losses. Risk treatment of already distressed slopes includes the four broad types of landslide remediation practices for slope stabilisation, namely: control works, restraint works, slope protection works and mass improvement techniques. Mitigation measures for landslide dams have been given special attention as a large portion of the hazard prone area in the Himalayas is susceptible to the formation of such dams with disastrous possibilities. Protecting heritage structures from landslide damage has also been given due attention. 1. LANDSLIDES – INDIA
India has a sensational record of catastrophes due to landslides, unique and unparalleled. Landslides & Avalanches are among the major hydro-geological hazards that affect large parts of India, especially the Himalayas, the Northeastern hill ranges, the Western Ghats, the Nilgiris, the Eastern Ghats and the Vindhyas, in that order. In the Himalayas alone, one could find landslides of every fame, name and description- big and small, quick and creeping, ancient and new. The north-eastern region is badly affected by landslide problems of a bewildering variety. Landslides in the Darjeeling district of West Bengal as also those in Sikkim, Tripura, Meghalaya, Assam, Nagaland and Arunachal Pradesh pose chronic
