Special Issue Information

Dear Colleagues,

Hydrodynamic-driven landslides, induced by seepage forces from rainfall or reservoir water level fluctuations, have emerged as a prominent area of geohazard research. The function of water within the landslide mass is highly significant. Consequently, attaining high-precision predictions and the efficient control of landslides necessitates an extensive knowledge of water within the landslide. For this purpose, this Special Issue provides a platform for the publication of advancements focused on numerical simulation, mechanical analysis, and constitutive development related to hydrodynamic-driven landslide processes. Meanwhile, we welcome the use of advanced monitoring technologies and artificial intelligence methods to conduct research on the prediction and prevention of hydrodynamic-driven landslides.

We anticipate that this Special Issue will encompass a diverse and high-quality collection of articles that can contribute to the knowledge and scientific progress in this field. By sharing innovative research and methodologies, we aim to enhance the understanding of hydrodynamic-driven landslides and improve the effectiveness of landslide risk management strategies.

This study investigated the deformation characteristics and mechanisms of the Baiyansizu landslide under the coupled effects of crack development, rainfall infiltration, and road loading. Numerical simulations were performed using GeoStudio software (Version 2018; Seequent, 2018) to analyze geological factors and external disturbances affecting landslide deformation and seepage dynamics. Four additional landslides (Tanjiawan, Bazimen, Tudiling, and Chengnan) were selected as comparative cases to investigate differences in deformation characteristics and mechanisms across these cases. The results demonstrate that rear-edge deformation of the Baiyansizu landslide was predominantly governed by rainfall patterns, with effective rainfall exhibiting a dual regulatory mechanism: long-term rainfall reduced shear strength through sustained infiltration-induced progressive creep, whereas short-term rainstorms generated step-like deformation via transient pore water pressure amplification. GeoStudio simulations further revealed multi-physics coupling mechanisms and nonlinear stability evolution controls. These findings highlight that rear-edge fissures substantially amplify rainfall infiltration efficiency, thereby establishing these features as the predominant deformation determinant. Road loading was observed to accelerate shallow landslide deformation, with stability coefficient threshold values triggering accelerated creep phases when thresholds were exceeded. Through comparative analysis of five typical landslide cases, it was demonstrated that interactions between geological factors and external disturbances resulted in distinct deformation characteristics and mechanisms. Variations in landslide thickness, crack evolution, road loading magnitudes, and rainfall infiltration characteristics were identified as critical factors influencing deformation patterns. This research provides significant empirical insights and theoretical frameworks for landslide monitoring and early warning system development. Full article

Since the impoundment of the Baihetan Reservoir, water-involved landslides have become widespread. Existing studies on landslide-generated waves have rarely examined the impact of varying water levels on wave characteristics. This paper focuses on the Wangjiashan (WJS) landslide in the Baihetan Reservoir area of China, conducting geomechanical experiments to investigate the spatiotemporal evolution of landslide-generated waves under different water level conditions. Utilizing a self-developed experimental measurement system, this study accurately records key parameters during the generation, propagation, and run-up of landslide-generated waves. It captures the complete sliding process of the WJS landslide under various water level conditions and elucidates the spatiotemporal distribution patterns of waves throughout their entire lifecycle, from generation through propagation to run-up. The research results indicate that water level factors significantly influence key parameters such as initial wave height, run-up on the opposite bank, propagation characteristics along the course, and maximum run-up in the Xiangbiling residential area. Generally, wave height initially increases and then decreases as the water level drops. Furthermore, this study offers crucial experimental data to deepen the understanding of the physical mechanisms of landslide-generated waves, advancing landslide disaster early warning technologies and enhancing the scientific accuracy and precision of landslide risk management.
