dataTestthat

<p>List with soil water contents (th) and unsaturated hydraulic conductivity values (ku) for spezific parameter of the uni- and bimodal hydraulic functions
of van Genuchten and Peters-Durner-Iden (PDI).</p>

datasets

Provides functions for (1) soil water retention (SWC) and unsaturated hydraulic conductivity (Ku) (van Genuchten-Mualem (vGM or vG) [1, 2], Peters-Durner-Iden (PDI) [3, 4, 5], Brooks and Corey (bc) [8]), (2) fitting of parameter for SWC  and/or Ku using Shuffled Complex Evolution (SCE) optimisation and (3) calculation of soil hydraulic properties (Ku and soil water contents) based on the simplified evaporation method (SEM) [6, 7].
