Multi-Year Variation Characteristics and Driving Forces of Groundwater Levels in the Yibin Area, Southern Sichuan, China

To support groundwater protection and sustainable utilization in southern Sichuan, this study aims to clarify the multi-year variation characteristics of groundwater levels (GWLs) and identify their main driving factors in the Yibin region. In this paper, 2019–2024 GWL monitoring...

Experimental study and model prediction of acoustic wave dispersion and attenuation in medium-coarse sandy sediments

A comparable joint dataset of compressional-wave (P-wave) and shear-wave (S-wave) speed and attenuation for saturated Ottawa sand under consistent sample conditions was obtained, using a dual-probe acoustic measurement method (DPAMM) for P-waves (20–150 kHz) and bender element (B...

Water Transport Characteristics and Their Impaction on Stability of Unsaturated Xiashu Loess Slopes During the Entire Process of Rainfall Infiltration

The Xiashu loess in the middle and lower reaches of the Yangtze River with typical aeolian characteristics is widely distributed in the hilly areas and is the main kind of landslides in this area. The paper reveals the infiltration process of the Xiashu loess slope under differen...

Strength enhancement and microstructural evolutions of dredged slurry stabilized with waste-modified composite binder

Dredged slurry with high water content and low permeability is prone to drainage clogging during vacuum preloading, limiting its direct use in land reclamation and typically requiring cement-based treatment. To explore a lower-carbon alternative to conventional treatment, this st...
