Figure 3: Fitted SWRC for soil water contents at soil matric potentials for the (a) summit, (b) backslope, and (c) toeslope positions averaged across two hillslopes using the Campbell (CA) model with absent parameter, and Brooks-Corey (BC), five- and four-parameter van Genuchten (VG5 and VG4), Tani (TA), and Russo (RU) models with estimated as one of the fitted parameters. Error bars are SE for six water retention measurements.
