ISPRS International Journal of Geo-Information, 2019 Accurate digital soil mapping (DSM) of soil organic carbon (SOC) is still a challenging subject because of its spatial variability and dependency. This study is aimed at comparing six typical methods in three types of DSM techniques for SOC mapping in an

Water Resources Research, Volume 62, Issue 7, July 2026.Abstract Alluvial systems are dynamic, structurally complex environments. Groundwater that is extracted from these systems is widely used for domestic consumption. Numerical models play an important role in the management of this extraction. To provide support for decision‐making, models must assimilate data that inform the spatial and temporal ...

International Journal of Advanced Robotic Systems, 2013 Geostatistics has been successfully used to analyse and characterize the spatial variability of environmental properties. Besides providing estimated values at unsampled locations, geostatistics measures the accuracy of the estimate, which is a ...

Water Resources Research, Volume 62, Issue 7, July 2026.Abstract The spatial correlation of streamflow in a river network captures how flows at different locations relate to one another and influence the downstream response. In this study, we analyze the spatial correlation of streamflow and rainfall during storm events in three Texas watersheds: San Antonio (2015 and 2016 storms), Guadalupe (2018 storm ...

Top-kriging - geostatistics on stream networks [PDF]
Hydrology and Earth System Sciences, 2006 We present Top-kriging, or topological kriging, as a method for estimating streamflow-related variables in ungauged catchments. It takes both the area and the nested nature of catchments into account.

Soil Use and Management, Volume 42, Issue 3, July‐September 2026.ABSTRACT Sustainable soil management in arid regions is constrained by the limited translation of subgroup‐level soil taxonomy into site‐specific agronomic recommendations. Hence, this study integrated field observations and laboratory analyses from 18 soil profiles with freely available Google Earth Engine (GEE) datasets.

Long‐Term Variability and Spatial Differentiation of the Frost‐Free Period in Iceland
International Journal of Climatology, Volume 46, Issue 8, 30 June 2026.Warming in Iceland (May–September) is expressed as fewer Tmin < 0°C days in the interior and more Tmin > 0°C days along the coasts. ABSTRACT Climate change in subarctic regions leads to significant transformations in thermal conditions; however, the long‐term variability of the frost‐free season (FFS)—and consequently, the growing period—remains poorly

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 ...
