## Abstract The portable surface capacitance insertion probe was used to measure the __in situ__ water content of near surface soil layers. The probe readings were calibrated against gravimetric samples collected over a wide range of water contents, and were found to be very closely correlated. The

The calibration of a capacitance sensor (operating at 80-150 MHz) for monitoring soil water content is described. The capacitance of two electrodes inserted into soil is used to measure the dielectric properties of the soil, soil water content being the principal factor influencing these properties.
A method of comparing the sound transmission characteristics of various materials, and combinations of materials, is presented, using a modified impedance tube technique. The procedure proved to be relatively quick and inexpensive in comparison with standard reverberation suite tests, and is therefo
## Abstract Timeβdomain reflectometry (TDR) sensors have been widely used in many fields for measurement of soil water content. However, few TDR sensors have been used in a hyperβarid environment (e.g. less than 0Β·05 m^3^ m^β3^), and such sensor applicability is not yet confirmed. In this study we
