standard deviation. In Figs. 2-5, the labeled points represent TSPs that at least
appear three times under the four water conditions. Regardless of water
condition, a common TSP can be found for p72 at UG 79 and for p22 at HG.
There are no common points at UG 99 and WG that can represent all water
conditions. However, except for the medium conditions, few more points are
included. We alternatively choose the common point under the three conditions
(all, wet and dry) for p41 at UG 99 and for p49 at WG. Thus there is at least one
point which can be selected at each plot under various water conditions. This
implies that even when data of several hydrological years or any water
conditions are included, a suitable soil moisture predictor from TSP can still be
obtained, which provides a basis to validate a hydraulic model.
