Open hardware portable dual-probe heat-pulse sensor for measuring soil thermal properties and water content

Laboratory Evaluation of the Dual-Probe Heat-Pulse Method for Measuring Soil Water Content

to evaluate the level of accuracy and precision that can be achieved with the DPHP method. Tarara and Ham The dual-probe heat-pulse (DPHP) method provides a means of (1997) conducted a laboratory experiment in which estimating volumetric soil water content ( ) and change in volumetric water content ( ) from measurements of volumetric heat capacity. DPHP-based estimates were compared with values...

Response of a New Soil Water Sensor to Variable Soil, Water Content, and Temperature

Thomas (1966) and later developed by Dean et al. (1987), whose work has lead to commercial soil water The success of time domain reflectometry (TDR) has led to the measuring instruments (Evett and Steiner, 1995; Paltidevelopment of other instruments that use the soil dielectric constant as the basis for determining volumetric soil water content. An example neanu and Starr, 1997). Readers are re...

Inverse Method for Simultaneous Determination of Soil Water Flux Density and Thermal Properties with a Penta-Needle Heat Pulse Probe

Indirect estimation of soil thermal properties and water flux using heat pulse probe measurements: Geometry and dispersion effects

[1] Traditionally, analytical solutions for heat transport in soils have been used in combination with heat pulse probe (HPP) measurements to estimate soil thermal properties. Although the analytical method has resulted in accurate estimation of soil thermal properties, we suggest that parameter estimation using inverse modeling (IM) provides new and unique opportunities for soil thermal charac...
