“…To forecast potential hazards from flow landslides, numerial models such as LS-RAPID, DAN3D, and Debris 2D are commonly utilized [18][19][20][21][22]. These models have been found to provide high accuracy results but are typically suitable for small-scale applications, such as slopes or small catchments, due to their demanding data, time, and economic requirements.…”

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.

“…Meanwhile, the construction of the railway changes the geological characterization, which has a great effect on the original stability factor and geological hazard susceptibility (Quang et al 2018;Xiong et al 2018). A large number of slope excavation during construction changes the original stable slope, which is an irreversible process (Kaya 2017;Hu and Ma 2018).…”

The Sichuan-Tibet Railway (STR) in China is of profound significance for Tibet's long-term development. Construction of railway reshapes the landscape it passes through and consequently influences the geological hazard risk. Despite the importance of railway construction, there remains a paucity of previous studies involving this factor. In this paper, we make a straightforward development on our previous study that a novel index system, notably considering the effect of railway construction is proposed for geological hazard assessment. Different from regional assessment, the concept of the line element is introduced, and the geological hazard risk along STR is comprehensively evaluated using matter-element extension model (MEEM), gray correlation model (GCM), and support vector machine (SVM). Receiver operating characteristic curve (ROC) analysis demonstrates that SVM performs better among the models. Results further indicate that a reduced performance of SVM in the ROC test appears to accompany with the absence of the construction factor. This finding highlights the essential role of construction in geological hazard assessment for the railway.
