2D sections of porosity and water saturation percent from combined resistivity and seismic surveys for hydrogeologic studies

Current uses of ground penetrating radar in groundwater-dependent ecosystems research

“…A combination of vertical electric soundings and ground penetrating radar (Khalil et al, 2010) has been implemented to infer 2D near-surface aquifer porosity and groundwater salinity. Resistivity and seismic refraction profiles have been combined to determine 2D near-surface porosity, water saturation, and volumetric water content (Mota and Monteiro dos Santos, 2006;Langston et al, 2011). Binley et al (2015) pointed out how geophysical techniques have become valuable to study near-surface hydrological processes over multiple spatial scales.…”

Electrical resistivity tomography and statistical analysis in landslide modelling: A conceptual approach

“…Despite of its simplicity, our approach, which has the advantage to be based on field data, allows us to determine which critical variations of ρ values associated to local slopes can cause landslides and their locations. Both a decrease of porosity in loose soils and an increase of the saturation degree can cause a decreasing of ρ (Mota and Dos Santos, 2006).…”

Environmental Geophysical Study of the Groundwater Mineralization in a Plot of the Cotonou Littoral Zone (South Benin)

“…Within the last decade, classic hydrogeological information has been increasingly complemented with subsurface geophysical information that allows obtaining more accurate images of aquifer systems [3][4][5][6][7][8]. This type of studies has led to the development of the hydrogeophysics discipline [9], in which geophysical methods are used for mapping aquifer subsurface features, estimating properties of the aquifer system, and monitoring distinct dynamic processes, such as seepage in the vadose zone, fluid flow direction, seawater intrusion, and pollutant migration [10].…”
