ABSTRACT:
The embodiments of the invention are directed to a new apparatus and method of measuring the water content using time domain reflectometry (TDR), or electrical conductivity in deep soil levels to. The method uses flat, flexible, waveguides attached to a flexible sleeve filled with a filling material which press the flexible waveguides against an irregularly shaped interior borehole wall.
