The soil erosion model presented in this paper is based predominantly on general physical principles. The model parameters are related directly to measurable soil, slope and rainfall properties. Both the erosion and the deposition of the soil
This paper discusses the validation of the physical-deterministic site model OPUS (SMITH and KNISEL 1985) which describes the water and matter fluxes in the soil and at the soil surface. In this study the submodels infiltration, water flux
in the soil and evapotranspiration have been tested using extensive data sets from a German research catchment. Furthermore, not only the applicability of this model but also the transferability have been examined by comparing different measurement sites.

A recent conceptual model, which refers to the seal layer in term of basic soil physics concepts (soil water retention and hydraulic conductivity-water content relationship), is applied to investigate the dynamic changes of the soil hydraulic
properties within the zone of the seal layer. Results of laboratory experiments in two soils, Sharon sandy loam (Hamra) and Ruhama loam (loess), were applied for the calibration of the model.
