Preferential percolation quantified by large water content sensors with artifactual macroporous envelopes

Popis výsledku v původním jazyce

For many scientific and practical tasks, it is important to estimate the soil?water percolation fluxes. This paper builds on measurements with large horizontal time-domain reflectometry water content sensors in a loamy Mollisol. The sensors were installed into pre-drilled holes and the gaps between them, and the soil was filled with a slurry of local soil with water. This gave rise to envelopes around them that contained artificial macropores. The sensors reacted to intensive rains by a rapid increase of their readings, often above the native soil?s porosity, followed by an almost equally rapid decrease. The paper explores the feasibility of quantifying the rapid percolation, based on these anomalous water content peaks, and demonstrates that this is possible in principle, if the processes are simulated by a suitable model. A two-dimensional dual porosity non-equilibrium (mobile-immobile) model was tried. The envelope around the sensor was modelled as an annulus with higher porosity an
