Landslide Character and Hydrological Thresholds for Slope Failure Initiation on Volcanic Scoria Slopes: Case Study From Mt Hobson/Ōhinerau, Auckland, New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
Rainfall‐induced landslides involving on Auckland Volcanic Field scoria cones are highly unusual, compared with widespread landsliding in the surrounding Auckland clay‐rich residual soils. Indeed, while Auckland can suffer from thousands of rainfall‐induced shallow landslides from severe storms at subdecadal timescales, these are usually limited to ...

Wheat Yield Response to Organic Fertilisers Depends on Drought Timing in a Sandy Soil

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 1, March 2026.
ABSTRACT Organic fertilisers enhance crop drought resilience by improving nitrogen (N) and phosphorus (P) use efficiency and soil‐plant water relations. However, the underlying mechanisms governing their effects across different drought timings in wheat under sandy soils remain unclear.

Compressional wave velocity and effective stress in unsaturated soil: Potential application for monitoring moisture conditions in vadose zone sediments

Vadose Zone Journal, 2021
Compressional seismic (P‐wave) velocities were measured experimentally at different matric suctions and confining pressure states using a variety of sediments collected from the USDOE Hanford Site in southeastern Washington State. The P‐wave velocity was

Revisiting the thermodynamics of hardening plasticity for unsaturated soils [PDF]

, 2010
A thermodynamically consistent extension of the constitutive equations of saturated soils to unsaturated conditions is often worked out through the use a unique 'effective' interstitial pressure, accounting equivalently for the pressures of the ...

Pseudo‐diffusivity characteristic curves for surface–rootzone soil hydrologic connectivity

Vadose Zone Journal, Volume 25, Issue 2, March/April 2026.
Abstract Accurate quantification of the rootzone soil moisture (θ) dynamics and hydrologic thresholds is important to advance sustainable agricultural water management and drought monitoring. Various low‐pass filters are popularly used to generate a first‐order approximation of θ, referred to here as θ̂$\hat{\theta }$, from temporally smoothed and ...

Experimental Study on Viscoplastic Property of Unsaturated Reticulate Red Clay Used as an Engineered Barrier

Geofluids, 2020
In this study, to explore the feasibility of a compacted red clay as an engineered barrier in landfills, the viscoplastic property of remodeled unsaturated reticulate red clay was studied through a series of triaxial tests.

Willow rotation rapidly improves key drainage properties of compacted organic soils

Vadose Zone Journal, Volume 25, Issue 2, March/April 2026.
Abstract Mechanical methods implemented to solve drainage issues caused by compacted layers in cultivated organic soils have produced only short‐term improvements. Limited research has been conducted on biological methods, particularly the use of plants as biological subsoilers.

Mitigating greenhouse gas emissions from a tropical sandy loam using oil palm empty fruit bunch biochar and compost amendments

Vadose Zone Journal, Volume 25, Issue 2, March/April 2026.
Abstract The role of biochar in mitigating greenhouse gas (GHG) emissions from tropical soils, especially when combined with compost, is still not adequately researched. This study evaluated the effects of oil palm empty fruit bunch (EFB) biochar applied at 10 and 20 t ha−1 (B10 and B20), compost at 20 t ha−1 (CP20) and in combination (B10CP20 and ...

Evaluation of 10 soil moisture profile sensors using a sandbox experiment

Vadose Zone Journal, Volume 25, Issue 2, March/April 2026.
Abstract Soil moisture profile sensors (SMPSs) are designed to measure the volumetric water content of soil at multiple depths simultaneously. Their vertical installation makes them particularly suitable for frequent relocation, as required for the use during cultivation of field crops.
