Evaluation
The additional data in the dry zone were measured by Lisa Heise within their thesis at TU Braun-
schweig /UMS Munich using a device made by Decagon (WP4C). They are documented in Heise's
thesis (http://www.soil.tubs.de/mitarbeiter/dipl_detail.php? id=78).
The pronounced air entry point and the steep drop down of the retention
•
curve after reaching the air entry point is characteristic of the sand.
The hydraulic conductivity can be determined only from pF 2.0, and then
•
drops down steeply.
Suitable models for data description are the Fayer-Simmons model, or the
•
bimodal model to describe the subsequent drop of the retention values
towards dehydration.
