| Zusammenfassung |
| Investigation of transient soil moisture profiles yields
valuable information of near- surface processes. A recently developed
reconstruction algorithm based on the telegraph equation allows the inverse
estimation of soil moisture profiles along coated, three rod TDR probes.
Laboratory experiments were carried out to prove the results of the
inversion and to understand the influence of probe rod deformation and solid
objects close to the probe in heterogeneous media. Differences in rod
geometry can lead to serious misinterpretations in the soil moisture
profile, but have small influence on the average soil moisture along the
probe. Solids in the integration volume have almost no effect on average
soil moisture, but result in locally slightly decreased moisture values.
Inverted profiles obtained in a loamy soil with a clay content of about
16% were in good agreement with independent measurements. |
