Two land-surface schemes, which differ only in the structure of the soil moisture prediction module, are compared. The first more complex model applies the Richards and heat diffusion equations for calculating soil moisture changes. The other, simpler model uses a diffusion type soil moisture module. All other components (atmospheric and vegetation parametrizations) are identical. In test runs the Cabauw data set was used. The resulting differences are studied in terms of both the annual mean and seasonal changes of energy and water fluxes. The preliminary results suggest that deviations imposed by structural differences in soil moisture prediction modules are not more significant than the deviations imposed by the differences in some relevant parametrizations. The results are useful to understand soil physical processes and to formulate soil moisture prediction modules.
