Assessing the Worth of Noble Gas Tracer Concentrations in Alluvial River‐Aquifer Systems Using Data Space Inversion

open access: yesWater 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 ...

Streamflow Spatial Correlation Length Increases During Storms and Its Application in Data Assimilation Improves Streamflow Predictions

open access: yesWater 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 ...

Sickles and forks: traditional rural knowledge of agricultural practices and its possible applications in archaeology

open access: yes, 2017
This paper presents the results of ethnographic observations of non-mechanized crop-processing activities at two localities in Catalonia (Spain). The aim of the study is to analyze the patterns of phytolith deposition on threshing floors and to be able ...

Quantifying mean grades and uncertainties from the ratio of service variables: accumulation to thickness. Applied to a phosphate deposit in Southern Mato Grosso, Brazil

open access: yesREM: International Engineering Journal
Estimating mineral resources of a stratiform mineral deposit is not always a simple activity. Some difficulties can arise in mineral deposits where the thickness is relatively much smaller than the dimensions in the horizontal plane, or because these ...

Integrating Soil Taxonomy With Soil and Remote Sensing Indices for Site‐Specific Management in the Egyptian Nile Delta Fringes

open access: yesSoil 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

open access: yesInternational 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

Non linear geostatistic approach to the daily rainfall data modelling

open access: yes, 2007
The environmental data modeling have often to deal with non linear problems such as: the probability estimation to overcome a given threshold and long tale distribution.

Effects of hypoxia on benthic macrofauna and bioturbation in the Estuary and Gulf of St. Lawrence, Canada [PDF]

open access: yes, 2010
The bottom water in the 4300 m deep Lower St. Lawrence Estuary (LSLE) is persistently hypoxic in contrast to the normoxic bottom waters in the Gulf of St. Lawrence (GSL). We photographed the seabed at 11 stations in the Estuary and Gulf of St.
