Soil structure determined from interrelationships in hydraulic, thermal and electrical properties

The presentation will focus on the interrelationships of soil hydraulic, thermal and electrical transport properties. We will highlight how some more easily measured transport properties can be used as surrogates for others, which cannot be readily measured. We will specifically illustrate how the thermo-TDR sensing platform can be used to collect detailed in situ thermal and electrical property measurements at millimeter to profile scale. We will utilize the interrelationships between hydraulic, thermal and electrical properties together with thermo-TDR measurements in order to demonstrate how soil density and structure can be determined in situ. We will also highlight opportunities for extending such approaches to other sensing platforms at other scales.
