- Soil hydraulic parameters and thickness were deduced from texture of available data (> 30 samples of soils in the typical steppe land use unit of the Xilin river catchment) after Clapp and Hornberger (1978), provided by Federer (2002), the most important soil parameter input for BROOK90 are stone fraction (S), matrix potential at field capacity (ψf,), volumetric water content at field capacity (θf), porosity / water content at saturation (θs), hydraulic conductivity at field capacity (Kf).
