Abstracts

In this study, the main aim is to apply SMCE (Spatial Multi-Criteria Evaluation) and Flow-R models to predict flow landslide susceptibility and hazard in Tam Chung commune, Thanh Hoa province (Vietnam). For this, nine factor maps including slope, relief amplitude, elevation, drainage density, engineering geology, groundwater availability, land cover, lineament density, and weathering crust type were collected and prepared for generation of landslide susceptibility map using the weights generated from the SMCE model.  Flow-R model was then used to forecast potential hazards related to the movement of flow landslide material. Landslde inventory collected from field survey was used to validate the landslide susceptibility and hazard maps. Results of this study showed that the susceptibility map, generated by applying the SMCE model, showed a high level of accuracy. By integrating detailed field surveys with the Flow-R model, the study identifies areas with low susceptibility to landslides but high vulnerability to material displacement. This study is helpful and supportive for better landslide hazard management in the study area, and facilitating informed decision-making in disaster prevention and mitigation.
