Figure 1: 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 constrained to measured values at −1.5 MPa. Error bars are SE for six water retention measurements.
