Many infiltration models rely on an effective hydraulic conductivity parameter (K e ) which is often determined in the field from rainfall simulation experiments on small plots. K e can be defined as the spatially averaged infiltration capacity when the soil is ‘field-saturated’ and steady state is reached. Then it equals the infiltration rate (f), provided ponding occurs. When a homogeneous...
Effective hydraulic conductivity (Ke) can be estimated with statistical models derived from datasets of field measured conductivities. Pedotransfer functions (PTFs) estimate constant Ke values, but suffer from large prediction errors because the functions usually do not account for soil structural heterogeneities. Rainfall‐runoff data have shown that the effective hydraulic conductivity, defined as...
