Abstract

This study integrates debris-flow susceptibility mapping with RAMMS numerical modeling for the Chokheltkhevi River basin, Georgia. Field surveys, GIS analysis, and laboratory data supported simulations of multiple release volumes. Results identify high hazard extending to the Aragvi confluence, threatening Chokhelni village, the Georgian Military Road, and infrastructure.
