Properties and effects of measurement errors on 2D resistivity imaging surveyingABSTRACT Electrode spacing errors and errors correlated with the magnitude of the observed potential are two key factors that affect the data quality for DC resistivity imaging measurements. This paper investigates the properties and effects of these two kinds of error on 2D resistivity imaging or inversion for practical applications. By analytic analysis and numeri... ... hiện toàn bộ

Weathering variations in a granitic massif and related geotechnical properties through seismic and electrical resistivity methodsABSTRACT Mapping and distribution with depth of alteration in rocks is critical in engineering planning because it has a fundamental impact on the geotechnical properties of the materials. Lateral heterogeneity on a weathered rock massif makes boreholes inadequate for its complete characterization. Geophysical methods increase spatial sampling along the study area a... ... hiện toàn bộ

Effective medium theories for modelling the relationships between electromagnetic properties and hydrological variables in geomaterials: a reviewABSTRACT The paper reviews the effective medium theories used for modelling the relationships between electromagnetic properties (low‐frequency conductivity and high‐frequency permittivity) and hydrological variables (water content, salinity, suction, permeability) in soils and rocks. It aims a) to provide a simple presentation of these theoretical approaches, b) to... ... hiện toàn bộ

Combination of 1D laterally constrained inversion and 2D smooth inversion of resistivity data with a priori data from boreholesABSTRACT Resistivity imaging in combination with borehole information is a powerful tool for site investigation. We show that the combination of 1D laterally constrained inversion (1D‐LCI) with the use of a priori information from borehole data and 2D smooth inversion adds significant value to the interpretation of continuous vertical elec... ... hiện toàn bộ

Spectral Induced Polarization (SIP) signatures of clayey soils containing tolueneABSTRACT We performed laboratory experiments to investigate the sensitivity of the Spectral Induced Polarization (SIP) method to toluene contamination in clayey soils. We used mixtures of quartzitic sand and montmorillonite as soil samples, artificially contaminated with varying amounts of toluene. Care was taken to quantify the experimental uncertainty resulting fr... ... hiện toàn bộ

Electrical properties of clay in relation to moisture lossABSTRACT Subsidence of buildings situated on clay soils can be a serious insurance problem in dry summers. In order to investigate subsidence and monitor its progress, non‐invasive techniques that provide information on soil properties have enormous potential. To help assess the application of new electrical tomographic monitoring techniques, the electrical properti... ... hiện toàn bộ

S‐wave velocity structure of Chlef City, Algeria, by inversion of Rayleigh wave ellipticityABSTRACT Chlef City, Algeria, which is located in the Lower Cheliff Basin, is vulnerable to seismic hazards. Since there is no constrained velocity model for the Lower Cheliff Basin, particularly at greater depths, we conducted an ambient vibration investigation to map the shear‐wave velocity structure beneath the city, with the primary goal of supplementing the exi... ... hiện toàn bộ

Coupling hydrogeophysics with hydrodynamic modelling to infer subsurface hydraulic architecture of an alluvial floodplainABSTRACT This paper underscores the importance of spatially dense geophysical data sets for making informed decisions in water management strategies. Such decisions may require understanding how site‐specific subsurface architecture – especially hydraulic connectivity – impacts the response of a shallow aquifer to anthropogenic hydrologic disturbances (e.g. over‐pum... ... hiện toàn bộ
