A study is reported which investigates the use of commercial ultrasonics to determine moisture content in geologic and similar materials. Transmission experiments were performed on two of the limiting extremes found in these types of media. In one, tests were made on moistened sand. In the other, fractured media were experimentally simulated with a stack of ceramic tiles with gaps filled with and without water. A simple theoretical model has been developed to estimate velocities and transmitted amplitudes through the tile system, and calculations from this model are compared to the experimental data. It appears that ultrasonics are more sensitive to moisture content in systems where the amount of granular materials is small compared to consolidated media.
