Special Issue Information

Dear Colleagues,

Water-induced landslides, being prevalent geohazards in reservoir areas and areas with high rainfall intensity, hold great theoretical significance and engineering application value, making their identification and mitigation research essential. In recent years, advancing the fundamental theories and practical applications in approaches to water-induced landslide hazard risk forecasting and assessment has become crucial. Investigating and monitoring water-induced landslides emphasizes early identification, stability evaluation, prediction, and prevention of these hazards. Stability and risk assessments focus on identifying and mitigating the risks associated with potential water-induced landslides, providing essential information for planning and emergency response.

Therefore, this Special Issue aims to present original research and review articles that present innovative approaches for analyzing stability, predicting failure mechanisms, designing effective stabilization measures, and assessing risks of water-induced landslides. We particularly encourage researchers and practitioners to share their knowledge, experiences, and research outcomes related to water-inducedwater-induced landslide forecasting, assessment, and early warning.

Potential topics include, but are not limited to, the following:

  • Multi-source remote sensing for water-induced landslide identification
  • Laboratory testing methods on soil and rock behaviors related to water-induced landslide
  • Advances in sensors and monitoring techniques for water-induced landslides
  • Water-induced landslide susceptibility mapping
  • Analytical, physical, and numerical techniques in water-induced landslide stability assessment
  • Physical model testing and numerical simulation of water-induced landslides
  • Water-induced landslide evolution mechanisms
  • Artificial intelligence applications in water-induced landslide hazard risk
  • Development of new early warning criteria for water-induced landslides
  • Comprehensive risk assessment and hazard evaluation of water-induced landslides
  • Digital twin-driven water-induced landslide disaster

We look forward to receiving your contributions.

The movement process of debris flow in the complex roads system is important for risk evaluation and emergency rescue. This paper presents an in-depth study of the diversion effect of debris flow in cross channels, a common branching structure in both natural and engineered environments, especially in the field of urban debris flow prevention. A mathematical model is established based on the conservation of mass, momentum, and energy, and a solid–liquid two-phase motion equation for debris flow is derived from two-phase flow theory. A numerical solution method, combining the finite difference method and finite volume method, is employed to discretize and solve the equation. The model’s validity and effectiveness are confirmed through a numerical simulation of a typical engineering case and comparison with existing experimental data or theoretical results. This study reveals that debris flow at cross channels exhibits a diversion phenomenon, with some debris flow continuing downstream along the main channel and some diverting into the branch channel. The diversion rate, defined as the ratio of outlet flow to inlet flow of the branch channel, indicates the magnitude of this effect. This research shows that the solid–liquid ratio, inflow, width ratio, height ratio, and angle of the cross channel significantly impact the diversion effect. A series of numerical simulations are conducted by altering these parameters as well as the physical properties of debris flow and boundary conditions. These simulations analyze changes in flow rate, velocity, pressure, and other parameters of debris flow at cross channels, providing insights into the factors and mechanisms influencing the diversion effect. This research offers a robust instrument for comprehending and forecasting the dynamics of urban debris flows. It contributes significantly to mitigating the effects of debris flows on city infrastructure and enhancing the safety of city dwellers. Full article
