Author: Dymphie Burger
The soil links atmospheric processes to the biosphere and its ability to transmit water is described by the hydraulic conductivity. The hydraulic conductivity at saturation (Ks) is a key parameter in hydrological models, but measuring Ks is time and labor intensive. Therefore Ks is often estimated by pedotransfer functions (PTFs), which are mostly empirical models that use easily available soil properties. However, these PTFs usually do not consider soil structure, which has a large influence on Ks, and thus might lead to underestimation of soils with larger intra-aggregate pores. This might lead to false estimations of runoff and infiltration, and we need accurate predictions to take appropriate water and soil management decisions. In this study, we developed a PTF that includes soil aggregation to predict the Ks.
