Abstract

A modelling concept is evaluated to predict the vertical transport of phosphate in the unsaturated zone corresponding to experimental data from a wastewater irrigation field test site. In contrast to deterministic models, compartment models are subject to several simplifying assumptions requiring a small data set. So the assumption of a time constant soil moisture profile is proved in calculating the water balance with a deterministic model. Based on measured phosphate distribution, different combinations of the KKeywords
