The Mae Chan River watershed, a watershed that is surrounded by high erodible mountains, is particularly vulnerable to landslides. This research aimed to assess the susceptibility of landslides in the unique watershed using the frequency ratio approach. Landslide inventory data were 173 landslide scars in the mountainous region of the watershed. The data were extracted from satellite images that captured historical landslide scars on its surface. Landslide causative factors were selected based on causative elements observed in the watershed that potentially caused the previous landslide occurrences. These inventory data and causative factors were combined to create a landslide susceptibility index and classes. The analysis indicated that around 36 % of the entire watershed was highly prone to landslides, especially in the northwestern and southern high mountains. The remaining 43% and 21% of the watershed's area were classified as moderate and low landslide susceptibility classes, respectively. The landslide susceptibility data's accuracy, reliability, and predictability were verified using the area under the receiver operating characteristic (ROC) curve (AUC) analysis. The AUC values represented the success and prediction rates curve of 0.738 and 0.712, respectively, suggesting that the model performed reasonably well in identifying and predicting landslide susceptibility classes. The study highlights the qualification of landslide susceptibility mapping in a watershed in Thailand to other large-scale landslide hazard research.</div></div>","PeriodicalId":34142,"journal":{"name":"Quaternary Science Advances","volume":"17 ","pages":"Article 100263"},"PeriodicalIF":2.9,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143175257","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Earlier studies have addressed its tectonic activity and metamorphic activation. However, the contribution of active tectonics to the geomorphic evolution of the region is less understood. Using the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Global Digital Elevation Model (GDEM) and Google Earth Imagery, various geomorphic features viz., alluvial fans, triangular facets, wineglass valleys, mountain fronts, knickpoints, and river terraces were identified and delineated. The study area was divided into three river sections viz., Suru, Doda, and Tsarap, running along or occasionally cutting across the strike of the ZSZ. The longitudinal river profiles suggest a relatively higher degree of tectonic activity along the Doda River, followed by the Tsarap and Suru Rivers. This spatial variation in the tectonic activity is also evident from the mountain front sinuosity index, wineglass valley index, triangular facets, and the morphometry of alluvial fans. Both the geomorphic features and morphometric parameters provide evidence of relative variation in the ZSZ activity along the Suru, Doda, and Tsarap River sections.

From cold tundra and steppe landscapes to forested habitats during climatic amelioration, these environmental changes significantly influenced Neanderthal settlement patterns and adaptive strategies.

Further stability analysis via the RocPlane program revealed that the crucial rock slope sections at RS2 are unstable under all anticipated conditions. However, the rock critical slope segment at RS4 remains stable under static dry, dynamic dry, and static saturated conditions and unstable under dynamic saturated conditions. Furthermore, a stability study was conducted via limit equilibrium and finite element methods for static dry, static saturated, dynamic dry, and dynamic saturated loading scenarios at crucial rock slope sections RS1 and RS5. This study's performance analysis of geometric profiles indicates that variations of slope height and slope angle lead to greater slope stability.
