The Hindu Kush-Himalaya (HKH) is geologically fragile with unstable slope-land systems. Every year, landslides and related hazards resulting from a combination of natural conditions and human activity cause thousands of deaths and several billion US$ in economic losses. Disaster mitigation requires better understanding of the physical nature of the region and the impact of human activity, with integration of knowledge from such diverse fields as geology, geophysics, engineering, hydrology, and meteorology, to facilitate more effective planning and implementation of activities.Written by professionals of repute with wide experience in the region, this book provides readers with information on the geology, physiography, seismicity, climate, and rainfall of the HKH region and their bearing on landslide problems, as well as on techniques for investigating landslides and landslide prone slopes and methods for mitigation. Four case studies in Nepal and China illustrate the integrated approach needed for successful mitigation and management of landslides and debris flows.The book provides useful reference material both for experts and for the medium level technical staff engaged in landslide hazard management and control in the HKH countries. It will also be useful for students of geology, civil engineering, geotechnical engineering, and other related subjects and as course material for academic and professional training courses on landslide management and control.
