Abstract

This study investigates the landslide area that affects approximately 52 hectares northwest of Çoraklı village center in Şavşat district, Artvin province, from a geomorphological perspective. The area was mapped using topographic maps, UAV-acquired images, orthophotos, and detailed field studies. The study area features Paleogene-aged volcanic sedimentary rocks and Eocene-clastic and carbonate rocks, which have high clay production potential, combined with steep slopes. Meteorological data indicate that this region receives more rainfall than its surroundings, creating favorable conditions for landslide formation. The landslide, occurring at elevations between 1,270 and 1,700 meters, started as a slide in higher areas and progressed as a debris flow toward the valley floor. The area is marked by a prominent main landslide scarp about 60 meters high, forming a crescent shape. The longest section of the landslide flank was 345 meters. The distance between the residential structures in Çoraklı village and the landslide crown was less than 20 meters. Fresh and flowtype mass movements were observed at the toe of the landslide and in nearby areas. The potential for existing landslides in this region underscores the urgent need for measures to be taken in this area of the Çoraklı settlement.
