Examines leak identification in geomembrane-lined irrigation reservoirs to reduce stored-water losses.
Paper details and full-text access →2025
Large-scale direct shear tests compare drainage-geocomposite interfaces with smooth and textured geomembranes at different moisture levels. Texture and wetting affect peak and large-displacement strength, supporting site-specific cap stability testing.
Paper details and full-text access →2024
Laboratory creep tests and modelling examine HDPE rupture at high tensile stress. The results highlight stress-dependent failure; accelerated high-stress tests are not a direct prediction of installed liner life.

Tests an HDPE liner after ten years at a gold tailings facility under different exposure conditions. Reports the sampled material’s mechanical response and identifies stress-crack performance as an area requiring further monitoring.
Paper details and full-text access →2024
Summarises laboratory interface friction tests relevant to shallow landfill covers. Failure mode, surface wear, fluid and soil density affect friction, so high-stress test results should not be assumed suitable for low-stress interfaces.

Reviews vegetation-based landfill covers alongside conventional clay and geosynthetic caps. Useful for comparing alternatives, with performance dependent on climate, soil thickness, vegetation and maintenance rather than a universal replacement for barrier liners.
Paper details and full-text access →2024
Reviews geomembrane leakage, defective seams, tailings permeability, lateral drainage and subgrade effects in tailings facilities. Section 6.2 covers BGM chemical durability and seam creep, alongside the review of HDPE and LLDPE liner performance and design considerations.
