Abstract

Electromagnetic techniques have been used for many years for the determination of moisture content in materials. We are adapting two of these techniques to the estimation of moisture in an unsaturated flow experiment. The two are the time domain reflectometry (TDR) and capacitance methods. A primary criterion for our experiments is that these techniques be noninvasive. In this regard, our application has a different requirement than most previous work. Some comparisons and contrasts to earlier applications are made to our requirements. We report here some measurements using the TDR technique noninvasively and speculate about the ability of these techniques to give the required resolution for data acquisition.
