Abstract
Soil texture and moisture content are necessary for cultivation, hydrology, hydrogeology, and geotechnical engineering. Spectral Induced Polarization (SIP) is a geophysical method used to measure the electrical properties of subsurface materials, such as soils and rocks, over a range of frequencies. It is a non-invasive technique that provides information about the physical and chemical properties of the subsurface. SIP provides a non-invasive technique for measuring soil moisture. This study focuses on Egypt's Vision 2023 Sustainable Development Goals. As the SIP method is sensitive to the presence of water in the soil matrix, it is especially useful for monitoring soil humidity and moisture. The electrical characteristics of soil are influenced by water, leading to alterations in impedance spectra. This paper surveys the principles of Spectral IP, its application in determining soil texture and moisture content, and offers experimental results that demonstrate its effectiveness. The electrical spectral measurements were made over a frequency range starting from 5 mHz up to 100 kHz. The important parameters of SIP are quadrature (imaginary) conductivity, phase angle, and chargeability were measured. Findings indicate that when the water content rises, the quadrature conductivity goes up, but the chargeability and phase angle go down. The results indicate that SIP is a successful approach for assessing soil because it can precisely detect soil moisture levels and consider soil texture characterizer.
