    Abstract

    Soil physical characteristics are important input parameters in modelling unsaturated flow in soils. Determining such characteristics in the laboratory is laborious and expensive. Instead, characteristics can be inferred from available soil data by class-pedotransfer functions. A comparison was made for six sites on sandy soils using the SWACROP model with input either from laboratory measurements or from a standard series. Simulation results did not differ significantly, implying that standard series can be used in studies like this for simulating the unsaturated water flow. Differences in specific criteria for individual sites were sometimes substantial, in which case it does make a difference which characteristics are used.
