Water content of geomaterials is an important property in geotechnical engineering. The electrical conductivities of common geomaterials are low. With the development of geoenvironmental engineering, highly conductive geomaterials such as contaminated soil and municipal solid waste (MSW) are of great concern by many researchers. Water content measuring and monitoring of geomaterials are very important for determination of geotechnical parameters, stability analysis, monitoring transport of pollutants, water...
