“…Soil salinization is becoming one of the harmful environmental threats that are damaging severely the natural environment, agricultural crops, human health, building, facilities and water supply systems [1][2][3]; Salt affected soils are developing gradually in many areas of the world, especially in arid and semi-arid regions. Recent studies have reported that over one billion hectares of land are affected by soil salinization [4][5][6][7] with a porftential of 10 to 16% increase/year [8][9][10]. In the next 30 years, the percentage of the total irrigated land affected by soil salinization could be extended to 50% if left unattended [7,11].…”

“…Moreover, the presence of salt can generate many damages on civil engineering infrastructures. The interaction between soluble salts in the soil solution and the exchange phase induces soil modifications, engendering soil strength diminution, swelling and dispersion, soil erosion and permeability reduction [10,12]. Since investigating the electrical response of soils is considered as a non destructive approach allowing precious information of soil [13][14][15][16], large uses have been employed for electrical measurements in many areas of scientific and engineering investigations, such as environmental, geotechnical, groundwater and underground fields.…”

Soil salinity is becoming one of the most devastating environmental hazards over the years. Soil investigation involves fast, low cost and non disturbing methods to measure soil characteristics for both construction projects as well as for agricultural use. The electrical resistivity of saline soils is greatly governed by salt concentration and the presence of moisture in soil matrix. Experimental results of this investigation highlight that there is a significant relationship between the electrical resistivity of soil samples mixed with chloride solutions (NaCl, KCl, and MgCl 2 ) at various concentrations, and soil physical properties. Correlations represented by quadratic functions were obtained between electrical resistivity and soil characteristics, namely, water content, degree of saturation and salt concentration. This research reveals that the obtained correlations between electrical resistivity, salt concentration, water content and degree of saturation are effective for predicting the characteristics of salt affected soils in practice, which constitute a governing element in the assessment of saline lands sustaining infrastructure.
