GIS-based statistical landslide susceptibility analysis a case study from the Bostanlik District, Uzbekistan

Keywords: Landslide, Bostanlik

Abstract

The Bostanlik district of Uzbekistan is mainly characterized by hills, mountains and highlands, whereby mountains cover almost the entire territory. The elevation of the district increases from west to east and from south to north. The southern and western parts of the area are on average at an elevation of 1000 m above sea level. The rest of the district is located between 1200 and 4000 m above sea level. The hills are formed mainly by sandstones and loess. Further, the Bostanlik district is one of the most landslide-prone areas of Uzbekistan. Most of the landslides are triggered by snow melting and precipitation. A significant number of landslides is located near a mountain reservoir (with possible causal relationships). Since the Bostanlik district is important in terms of touristic activities, the monitoring of existing landslides is necessary, and a landslide susceptibility zonation is highly recommended as a basis to mitigate the risk arising from these hazards.
