Geological and geotechnical challenges on the Great Dyke of Zimbabwe and their impact on hardrock pillar design

Deep Underground Science and Engineering, Volume 5, Issue 2, Page 506-538, June 2026.
The Great Dyke of Zimbabwe is notable for its rich platinum group metal deposits but poses significant geological and geotechnical challenges due to its complex rock types and structural features. Traditional pillar design methods are insufficient for addressing these complexities; the study suggests incorporating advanced techniques such as machine ...

Geostatistic application for the study of contaminated groundwater in broad industrial areas

, 2004
A geostatistic application is proposed for the realization of a hydraulic conductivity map in an abandoned industrial area, characterized by the extension of about 300 ha, in which a characterization study is in progress.

Comparing different approaches - data mining, geostatistic, and deterministic pedology - to assess the frequency of WRB Reference Soil Groups in the Italian soil regions [PDF]

, 2013
Estimating frequency of soil classes in map unit is always affected by some degree of uncertainty, especially at small scales, with a larger generalization. The aim of this study was to compare different possible approaches - data mining, geostatistic,

Random finite element analysis on ground subsidence caused by tunnel excavation in karst regions with spatial variable soil

Deep Underground Science and Engineering, Volume 5, Issue 2, Page 615-632, June 2026.
This study investigates ground subsidence during tunnel excavation in karst areas, highlighting the combined effects of karst cave proximity, cave size, and soil spatial variability. Findings suggest that shorter cave distances and larger cave sizes increase subsidence variability, and a modified Peck formula is proposed for more accurate subsidence ...

Produtividade do milho relacionada com a resistência mecânica à penetração do solo sob preparo convencional Relationship between maize yield and soil mechanical resistance to penetration under conventional tillage

Engenharia Agrícola, 2006
A resistência mecânica do solo à penetração exerce grande influência sobre o desenvolvimento vegetal, uma vez que o crescimento das raízes e a produtividade das culturas variam de forma inversamente proporcional ao seu valor.

Convection‐Permitting Regional Climate Simulations Reveal Stronger Drying and Snow Loss in Semi‐Arid Mountainous Basins of Morocco

Hydrological Processes, Volume 40, Issue 6, June 2026.
Convection‐permitting simulations (WRF3, 3 km) better represent mountain precipitation and snow processes than coarser regional simulations (WRF20, 20 km). Hydrological simulations forced by WRF3 improve streamflow seasonality and snow‐related hydrological signatures compared to WRF20.

VERTICAL DISTRIBUTION AND SPATIAL PATTERN OF FINE ROOT DENSITY IN COFFEE – BASED AGROFORESTRY SYSTEMS UNDER ORGANIC AND CONVENTIONAL INPUTS

Tropical and Subtropical Agroecosystems, 2018
This research shows results on spatial changes of fine roots (d < 2.0 mm) in two Coffea arabica- shade tree associations: coffee shaded by a) Abarema idiopoda (timber and nitrogen fixing tree), and b) Terminalia amazonia (timber tree). These associations

Fine‐Scale Spatial Variation of Evapotranspiration Across Tropical Land‐Cover Mosaics Revealed by UAV Thermography

Hydrological Processes, Volume 40, Issue 6, June 2026.
We study evapotranspiration (ET), a key flux in the hydrological cycle, across heterogeneous tropical land‐cover mosaics in lowland Sumatra featuring secondary forest patches, oil palm plantations, and shrubland. We apply high‐resolution UAV thermography and an energy‐balance model to derive ET across three mosaic landscapes (Areas 1–3).
