Landslide hazard susceptibility mapping based on terrain and climatic factors for tropical monsoon regions (original) (raw)

Abstract

Deep weathering, residual material (colluvium) and random rainfall intensity are mainly responsible for landslides in tropical monsoon regions. These parameters are often not taken into consideration in a landslide susceptibility assessment. Sustainable resources development in this region requires information on the spatial distribution of areas susceptible to landslides. This study highlights various aspects of the landslides that take place on the west coast of India and a methodology developed for landslide susceptibility mapping.

Résumé

Une altération météorique intense du substratum, des formations résiduelles et colluvions, des intensités de pluies aléatoires, sont les principaux facteurs responsables des glissements de terrain dans les régions tropicales de mousson. Les conditions d'un développement durable de ces régions nécessitent des informations sur la répartition spatiale des zones sujettes aux glissements de terrain. Ces facteurs ne sont pas pris en considération dans la pratique de la cartographie de l'aléa glissement de terrain. Cette étude met en lumière divers aspects propres aux glissements qui ont lieu sur la côte ouest de l'Inde, ainsi que la méthodologie développée pour cet objectif.
