Studies of the use of time domain reflectometry to determine moisture content in finite regions

This thesis addresses several questions related to the sensitivity of TDR to the determination of the moisture in laboratory experiments where the measurement is done noninvasively; Some tests were performed on moistened sand in a plastic box, treating the moisture content as the independent variable. Another set of tests was performed on moistened sand in a plastic tube to find the relationship between the outputs from the TDR with moisture content in systems both with and without water outflow. In addition, a set of tests was performed on a layered arrangement of large household ceramic tiles where the gaps between the tiles were or were not saturated with water. In all these tests, it is shown that TDR is effective to measure the moisture content noninvasively; A numerical analysis of a geometry related to those studied experimentally has been performed. Results show the effect of gap location on the TDR indication.
