Summary: A novel method is proposed in this study to evaluate rainfall-induced movements of landslides in the presence of stabilizing piles, using a water balance equation and motion equation. The method is attractive from an engineering perspective, as it can be readily implemented and requires few input parameters, making it suitable for predicting landslide movements in relation to rainfall scenarios.

Summary: This study found that the implementation of a siphon drainage system in a volcanic hillslope can effectively reduce groundwater levels in landslide areas and increase the stability of the slopes. Results from long-term field experiments showed that the siphon drainage system was able to prevent groundwater levels from rising during rainfall, indicating its effectiveness in maintaining stability.

Summary: Understanding changes in hydraulic properties of the subsurface is crucial for identifying areas prone to groundwater accumulation and landslides. This study demonstrates the possibility of estimating hydraulic conductivity using induced polarization (IP) measurements in both laboratory and field settings. The results also show clear frequency-dependent variations in electrical properties, which can be accounted for by fitting a Cole-Cole model. The findings provide enhanced resolution of hydraulic conductivity and reveal important subsurface characteristics related to drainage and instability.

Summary: The clogging issue of drainage holes in slope retaining walls along expressways threatens the safety and stability of the walls. This research conducted model tests and theoretical analysis to demonstrate the clogging problem and the anti-clogging ability of siphon drainage. The application of siphon drainage successfully reduced the groundwater level and showed no signs of clogging during the four-month operation, proving its effectiveness in treating leakage hazards.

Summary: This study uses the TRIGRS model to demarcate areas prone to rainfall-induced shallow landslides in a certain region of China. By inputting engineering geological and geotechnical characteristic data, the slope stability is simulated and verified. The results show a gradual decrease in slope stability under the influence of precipitation, with an increase in the percentage of slope area with a factor of safety less than 1.0. The findings can be used for hazards mitigation in the region.

Summary: This paper presents a methodology for estimating water stream obstruction caused by rainfall-induced shallow landslides. The landslide hazard was assessed using the SLIDE model, while rainfall patterns were estimated using a Log Normal Model. The resulting high hazard areas were identified for simulation of debris flow and analysis of river channel obstructions using the RAMMS-DF and Iber models, respectively.

Summary: Landslides are common geological hazards in the Three Gorges Reservoir Area (TGRA), and understanding their deformation mechanisms is crucial for prevention and control. This study focuses on the Zhangjiacitang landslide and analyzes the relationship between deformation and water level fluctuations and rainfall. The findings suggest that heavy rainfall is the main trigger for the landslide deformation, while the impact of water level changes is more complex. Monitoring during heavy rainfall and rapid water level decline periods is necessary.

Summary: This study analyzed a rainfall-induced landslide event in China on August 21, 2020, using various methods to reveal the characteristics, causes, consequences, and mechanisms of the landslide. The study found that the movement of the landslide exhibited a multiple-stage failure type and was directly influenced by antecedent cumulative rainfall.

Summary: Rainfall plays a crucial role in triggering landslides in many areas. Understanding the relationship between rainfall characteristics and slope stability is essential for mitigating landslide risks. Previous studies have shown that there exists a threshold curve of rainfall intensity and duration for a specific slope, beyond which landslides are expected to occur. This study aims to overcome the limitations and assumptions of previous research and investigate the rainfall intensity-duration control of landslides using real slope case histories and rainfall records. A generalized procedure called the critical rainfall pattern curve (CRPC) is proposed, which provides a simple yet effective tool for slope-specific landslide prediction and risk assessment.

Summary: Model tests were conducted on plain soil slopes and bamboo-rooted slopes to analyze slope surface displacement, earth pressure changes, and failure modes under slope top loading. The study also examined the impact of rainfall on deformation and mechanical properties of bamboo-rooted slope sliding. Results showed that the failure mode of plain soil slopes was block sliding, while bamboo-rooted slopes experienced progressive backward failure. The presence of bamboo rhizomes had a limited impact on slope displacement but significantly contributed to the sliding area's increase. The tests have important implications for the study of instability and disaster prevention in bamboo forest areas.

Summary: On the 26th of November 2022, heavy rainfall triggered diffuse landslides in the Northern sector of Ischia. This study investigated the characteristics of a debris flow that occurred in Casamicciola Terme Municipality. The debris flow originated from the Northern slope of Mt. Epomeo and caused significant damage to buildings, resulting in casualties, injuries, displacement, and severe damage to the road network. The study used field investigations, environmental data, and numerical models to assess the event and emphasized the need for careful monitoring and risk management activities in the future.

Summary: This study presents an analysis of a landslide that occurred in Calabria, Southern Italy in 2014. The triggering mechanism and evolution of the landslide are investigated using the material point method and a strain-softening Mohr-Coulomb constitutive model. The numerical simulation accurately reproduces the observed failure surface, displacement magnitude, and final configuration of the landslide body. The findings contribute to the prediction and prevention of similar landslides.

Summary: Slope movements can be classified into four phases: pre-failure, failure, post-failure, and eventual reactivation. Traditional numerical techniques are not suitable for analyzing the post-failure stage due to the large deformations involved. In this study, the material point method (MPM) is used to analyze a landslide in sensitive clays, with satisfactory results compared to field observation.
