This however, also involves prior paired measurements of soil water content and potential. More recently Karkanis (1983) and Dahiya et al. (1988) have explored an alternative and simpler approach for estimating field capacity and wilting

The upper boundary condi-tion for soil moisture is the infiltration rate, which is computed as the residual of precipitation minus surface runoff and parameterized through a simple TOPMODEL-based runoff scheme (Niu et al., 2005).

WebClapp&Hornberger K s values are significantly higher than those estimated by the Weynants PTF, “Toth class,” and Cosby SC and SSC, yet did not show any high outliers for E a fluxes. Interestingly, Cosby SC and SSC were developed based on the same water retention and K s data as Clapp&Hornberger, as both used data from Holtan et al.
