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