Fig. 4. Time average plots of ranked relative soil moisture content deviated from the catchment-wide mean value at four monitoring depths. Vertical bars correspond to the associated temporal standard deviation for the 1-yr monitoring period. Site numbers refer to the monitoring locations indicated in Fig. 2 and Table 2. A few sites with relatively large temporal standard deviation are identified using soil moisture clusters of dry (D1), moderately dry (D2), moderately wet (W2), or wet (W1) groups.
