Special Issue Information

Dear Colleagues,

Frequently, landslide hazards are caused by water, such as soil slump, debris flow, debris flood, avalanche, lateral spreading, landslide dam burst, etc. The prevention and mitigation of landslide hazards are needed to reduce losses. For this end, the water’s role in landslide hazards formation shall be first investigated and understood in order to commence further effective prevention and mitigation designs for landslide hazards.

In this Special Issue, papers focused on landslide hazards induced by water are welcomed. Research methods using numerical, field investigation, experimental and theoretical approaches to advance the understanding of landslide hazards formation are all encouraged. We also appreciate new techniques for monitoring, risk assessment, prewarning, prevention and mitigation.

Mountain disasters, such as landslides and debris flows, are becoming more prevalent due to abnormal weather patterns. Debris flows, triggered by heavy rainfall, are causing escalating damage to residential areas and roads as they surge down mountain streams. In order to both mitigate this damage and comprehend the underlying causes of such mountain disasters, comprehensive field investigations were carried out in regions where debris flows had transpired. To establish spatial information for analyzing vulnerable areas, GIS data were employed. Additionally, precise measurements of the actual extent of debris flow in targeted zones were obtained through the utilization of terrestrial LiDAR scanning. Subsequently, the process of debris flow was replicated using FLO-2D, a numerical model designed for such scenarios. This simulation incorporated actual rainfall data that had precipitated debris flow incidents, as well as probability-based rainfall data corresponding to return periods of 30, 50, and 100 years. Key parameters, including flow depth, velocity, and diffusion area, were compared across different scenarios. The sedimentation area of the section where debris flow originated, as determined from terrestrial LiDAR scan data, was estimated to be approximately 21,300 square meters. The outcomes of the FLO-2D simulation revealed that the diffusion area for Case I was approximately 20,900 m2, while the simulated diffusion area for a 100-year return period was calculated to be 40,725 m2. Furthermore, flow depth, velocity and diffusion area exhibited a gradual incremental trend in simulation results. Full article

Rainfall-induced shallow landslides cause damage to human activities and infrastructureseach year, and although the size of a landslide correlates to the damage that it causes, very few studies have previously investigated the factors that influence the size of a shallow landslide. The aim of this work was to assess the role of precipitation and land use in controlling the size of the source area of rainfall-induced shallow landslides. After ruling out the impact of the slope angle and bedrock lithology in the two selected catchments, the role of land use was investigated: the statistical tests showed that woodlands and vineyards had statistically different source area size distributions, possibly due to the different hydrological behaviours between the two. A correlation was additionally found between the size of a source area and the amount of cumulated rainfall in the three days prior to each analysed event. In both cases, an increase in source area size was linked to an increase in pore pressure. This study aimed to fill the existing gap in the research to help implement policies aimed at reducing the size, and consequently the impact, of shallow landslides. Full article
