Ten pedotransfer functions (PTF) estimating soil saturated hydraulic conductivity were investigated using the HunSODA database and the SOILarium 2.0 software. The predicting efficiency of the PTFs was investigated by using statistical indicators, such as the expected value of absolute as well as relative errors. The estimated values, along with measured values of two characteristic Hungarian sites were used in a model application for simulating infiltration during a heavy rainfall event. When choosing a pedotransfer function it is most safe to choose an empirical PTF or a PTF that was developed on a large base dataset applying a not-too-simple not-too-complex formula. Considering the uncertainty related to arbitrary choosing a PTF and using its estimation in a model application, it is more safer to measure than estimate the saturated hydraulic conductivity of the soil.
