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

open access: yes, 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.

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 ...

Knowledge gap on the spatial structure of soil nitrogen mineralization variability—A systematic review

open access: yesAgricultural &Environmental Letters, Volume 11, Issue 2, December 2026.
Abstract Soil nitrogen (N) mineralization governs plant‐available N from soil organic matter and microbial turnover, and is typically estimated as potentially mineralizable nitrogen (PMN) via anaerobic incubations or as N0 and mineralization rate (k) via long‐term aerobic incubations.

Uso da krigagem indicatriz na avaliação da probabilidade da produtividade de soja segundo os padrões regional, estadual e nacional = Indicator kriging application to evaluate the probable soybean productivity according to regional, state and national patterns

open access: yesActa Scientiarum. Agronomy, 2007
A Krigagem Indicatriz é um método de interpolação não linear que consiste na aplicação da Krigagem Ordinária sobre uma variável transformada, isto é, a variável resultante da aplicação de uma função indicadora dicotômica.

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

open access: yes, 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,

Suite of Regional Seismic Velocity Models for the U.S. Atlantic and Gulf Coastal Plains (CPVMv2.0): Incorporating Epistemic Uncertainty in Velocity Models

open access: yesEarthquake Spectra, Volume 42, Issue 4, November 2026.
The U.S. Atlantic and Gulf Coastal Plain (CP) sediments are kilometers‐thick, low‐velocity deposits underlain by high‐velocity bedrock that create regional patterns of amplification and attenuation of ground motions. Capturing these effects is challenging because of the limited subsurface information available, particularly the shear wave velocity (VS)

CyberShake NZ: Probabilistic Seismic Hazard Analysis in New Zealand Using Physics‐Based Ground‐Motion Simulations

open access: yesEarthquake Spectra, Volume 42, Issue 4, November 2026.
This study presents the computational components and workflow developed to conduct probabilistic seismic hazard analysis (PSHA) in New Zealand (NZ) using physics‐based ground‐motion simulations, referred to as “CyberShake NZ.” Semi‐automated procedures generate multiple realizations of kinematic rupture models, create rupture‐specific velocity models ...
