Measuring Soil Moisture in a Heterogeneous Field
Publication: World Environmental and Water Resources Congress 2009: Great Rivers
Abstract
This paper explores the theoretical basis, preliminary experimental results and potential benefits of using fiber optic technology for distributed measurement of field soil moisture. This technology determines soil moisture content by measurement of soil thermal response to a heat pulse. With a resolution of 1 m along a fiber optic cable this technique is capable of literally hundreds of measurements along a single cable installed at a specific depth. The technology is still under development at the time of this writing, but the indications are that it can quantify soil water variability with relatively high accuracy at moderate cost.
