“…The resistivity method is one of the oldest geophysical survey techniques (Schlumberger et al 1933;Archie 1942;Sumner 1976;Telford et al 1990;Loke 2011) and is commonly applied in fields such as engineering and environmental investigations (e.g., Zogała et al 2009;Pacanowski et al 2014;Amini and Ramazi 2016), geological (e.g., Shemang and Molwalefhe 2009;Barski and Mieszkowski 2014;Mieszkowski et al 2014) and hydrogeological (e.g., Asfahani and Abou Zakhem 2013;Giang et al 2013) studies. The purpose of electrical surveys is to determine the subsurface resistivity distribution by performing measurements on the ground surface.…”

Complex studies were carried out to recognize the fen structure and peat properties in the Całowanie Fen area, belonging to the Natura 2000 network. The studies were conducted in two study areas that differ significantly in terms of peat thickness. Electrical resistivity imaging (ERI) was used to identify the properties of the peat and its substrate, such as thickness and electrical resistivity. Comparison of the field studies with the laboratory tests has shown that the ash content rises electrical resistivity in peat. In addition, the study has shown that the application of non-invasive geophysical methods in protected areas is justified. The fen, as a medium containing mostly water, was a proper test area for the ERI measurements.

“…This study allowed to establish a simple relationship between electrical resistivity and porosity presented in Figures 8 and 9. Figure 12 presents the RCPT test results with calculated porosity according to Equation (6). The porosity values in the top and bottom of the layer result from water penetration, which gives higher electrical conductivity in these zones and affects the obtained lower porosity values.…”

“…Geophysical methods have been used for many years in prospecting for industrial and energy resources, geological and engineering surveys, as well as geotechnical surveys. Electrical resistivity, electromagnetic and seismic methods are commonly used in practical and research applications which include: geological [1][2][3][4] and hydrogeological [5][6][7] investigations of the subsoil, technical conditions of hydrotechnical structures and other civil engineering structures [8][9][10][11], testing of porosity [12][13][14][15][16][17], moisture content [18,19] and saturation degree [12,15,20,21] of the subsoil, as well as monitoring of landfills, and agricultural and post-industrial areas [22][23][24][25][26].…”

Standard test methods may not be suitable or sufficient for determining the geotechnical conditions of a structure’s subsoil and the effects of the designed structures on the environment. Geophysical test methods, validated with other methods, may prove useful. In recent years they have found many new applications in engineering practice, both geotechnical and environmental. The advantages of geophysical methods include the non-destructive and non-invasive nature of the tests, their low costs and quick results, as well as compatibility with different materials, including soils, solid rocks, wastes and anthropogenic formations. The paper presents the analysis of laboratory and field investigations including research in a modified oedometer, resistivity chamber, electrical resistivity tomography (ERT) and resistivity cone penetration test (RCPT). Laboratory tests allowed for the assessment of the degree of saturation and porosity of sandy and clayey soils. The tests were carried out on saturated and unsaturated soil samples and allowed for the determination of some relationships between electrical conductivity and porosity. The proposed equations were used to assess parameters in in situ studies using RCPT tests and showed good agreement with reference values based on undisturbed soil samples. ERT tests confirmed the usefulness of electrical measurements in the quality assurance of subsoil and hydrotechnical structures. The tests showed weakening zones in the levee body, discontinuity of the vertical sealing system on the modernized section of the embankment, and location of the top of clay deposits.

“…The results of soil resistivity tests for contaminated sites generally reveal a close relationship between free electrolytes, oils, and salt solutions [10][11][12][13][14][15], which are also the main components of leachate infiltrating from landfills. On the basis of the research results and gained experiences, the method for an assessment of environmental contamination for four independent landfills, was established and then verified.…”

Abstract:The paper presents complex analyses of geophysical site investigation results. The electrical resistivity method was used to investigate the potential pollutant migration pathways within areas of existing and former landfill sites. For the purpose of the present study, there were four municipal waste landfills and one industrial landfill chosen for further comprehensive analyses. The landfill bottom was isolated using geomembrane liner. However, ground water monitoring results revealed that the base was not leakage-free. Another two landfills were established in the past, when no containment systems were legally required. The geoelectrical investigation was the final part of an overall analytical assessment of the contaminated sites. The study was aimed at pollution spatial migration analyses and the interpretation of results, for further design of the reclamation and restoration plans. A clear correlation between pollution indicators such as salt compounds and electrical resistivity, allow aerial analyses and the precise determination of contaminated zones. The research results presented in the paper have been recently obtained and concern a period from 2010 to 2015.
