11. APPLICATION OF THE AHP MODEL TO ESTABLISH A LANDSLIDE PROBABILITY ZONING MAP IN A LUOI DISTRICT, THUA THIEN - HUE PROVINCE, VIETNAM

Hanh Nguyen Thi Thuy, Chuc Quach Thi

Giới thiệu

A Luoi is a mountainous district of Thua Thien Hue province, Vietnam, with rugged terrain, steep slopes, and many valleys. A Luoi district bears many risks of natural disasters such as storms, floods, droughts, and landslides yearly. This study applied the AHP (Analytical Hierarchy Process) model with the GIS tool on the input database of Sentinel-2B Image, DEM, and geographic background data to evaluate the influence of 5 factors: slope, elevation, aspect, land cover, and vegetation to generate a landslide hazard zoning map, scale 1:50,000. The results show that the sites with a high risk of landslides are concentrated mainly in the communes of Hong Kim, Hong Ha, Son Thuy, Hong Thuong, Phu Vinh, and Huong Nguyen. Thereby helping people avoid and minimize vulnerabilities caused by landslides.
