Evaluation of the Heat Pulse Ratio Method for Measuring Soil Water Flux

open access: yesSoil Science Society of America Journal, 2005
Soil water flux is an important hydrologic parameter, yet few techniques for measuring it in situ are available. Here we evaluate the heat pulse ratio method for measuring water flux. We conducted heat pulse measurements of flux in packed columns of sand, sandy loam, and silt loam soil.

A new method to measure Bowen ratios using high-resolution vertical dry and wet bulb temperature profiles [PDF]

open access: yesHydrology and Earth System Sciences, 2014
The Bowen ratio surface energy balance method is a relatively simple method to determine the latent heat flux and the actual land surface evaporation. The Bowen ratio method is based on the measurement of air temperature and vapour pressure gradients. If
