Abstract

Many researchers, in the recent years have developed various techniques for determining water content of the soils. Electrical Capacitance Volume Tomography (ECVT) is one of the techniques developed by using various types of sensors to improve the quality and effectiveness in the determination of water content in the soil. The technology is based on the capacitance measurement generated from a whole volumetric image of the region which is surrounded by three-dimensional geometry capacitance sensor. This study was carried out to determine the effectiveness of ECVT in measuring soil water contents in fine sand and silty sand to compared with the gravimetric method. Results analysis show that the correlations of the water content measurement R2 using ECVT and gravimetric methods for fine sand and silty sand are very good, about 0.978 and 0.988, respectively. These suggest that ECVT method has a good potential in determining the soil water content in this respective soil type.
