Performance of electrical spectroscopy using a RESPER probe to measure salinity and water content of concrete and terrestrial soil
Explorative Geophysics Concrete and Terrestrial Soil Non-destructive Testing Methods Electrical Resistivity and Salinity Permittivity and Volumetric Water Content
2015/8/27
This paper discusses the performance of electrical spectroscopy using a RESPER probe to measure the salinity s and volumetric content θW of the water in concrete or terrestrial soil. The RESPER probe ...
Soil-gas survey of liquefaction and collapsed caves during the Emilia seismic sequence
Gas geochemistry Geochemical exploration Gases Soil-gas measurements and monitoring Liquefaction
2015/8/26
The epicentral area of the Emilia seismic sequence is located in the Emilia-Romagna Region (northern Italy), 45 km from the city of Modena (Figure 1). This area is sited within thrust-related folds of...
Evaluation of soil thermal diffusivity algorithms at two equatorial sites in West Africa
Thermal diffusivity Soil temperature Soil moisture content West Africa
2015/8/18
This study presents comparisons between six algorithms used in the calculation of apparent thermal diffusivity (Kh) of the topsoil during measurement campaigns conducted at two equatorial sites. It fu...
Conventional tillage versus organic farming in relation to soil organic carbon stock in olive groves in Mediterranean rangelands (southern Spain)
Conventional tillage organic farming soil organic carbon stock olive groves Mediterranean rangelands
2015/1/6
Soil organic carbon (SOC) concentration is a soil variable subject to changes. The management system is a key factor that influences these changes. To determine the long-term effects of the management...
Short-term changes in soil Munsell colour value, organic matter content and soil water repellency after a spring grassland fire in Lithuania
Short-term changes soil Munsell colour value organic matter content soil water repellency spring grassland fire Lithuania
2015/1/6
Fire is a natural phenomenon with important implications on soil properties. The degree of this impact depends upon fire severity, the ecosystem affected, topography of the burned area and post-fire m...
Variations of soil profile characteristics due to varying time spans since ice retreat in the inner Nordfjord, western Norway
soil profile characteristics due varying time spans since ice retreat inner Nordfjord western Norway
2015/1/6
In the Erdalen and Bødalen drainage basins located in the inner Nordfjord in western Norway the soils were formed after deglaciation. The climate in the uppermost valley areas is sub-arctic ocean...
Factors driving the carbon mineralization priming effect in a sandy loam soil amended with different types of biochar
Factors driving the carbon mineralization priming sandy loam soil amended different types of biochar
2015/1/6
The effect of biochar on the soil carbon mineralization priming effect depends on the characteristics of the raw materials, production method and pyrolysis conditions. The goal of the present study is...
Seasonal changes in the soil hydrological and erosive response depending on aspect, vegetation type and soil water repellency in different Mediterranean microenvironments
soil hydrological erosive response
2015/1/5
Mediterranean areas are characterized by a strong spatial variability that makes the soil hydrological response highly complex. Moreover, Mediterranean climate has marked seasons that provoke dramat...
A joint inversion of apparent resistivity and peak-period of microtremor horizontal-to-vertical spectrum for shallow soil profile
microtremors horizontal-to-vertical spectrum S-wave velocity vertical electrical sounding resistivity simulated annealing
2009/3/5
We propose a new technique for a joint inversion of apparent resistivity data from a vertical electrical sounding and peak-period of spectral ratio of horizontal microtremors to vertical one in order ...
