O článku:
Stony soils are composed of two fractions (rock fragments and fine soil) with different hydrophysical
characteristics. Although stony soils are abundant in many catchments, their properties are still not well understood. This
manuscript presents an application of the simple methodology for deriving water retention properties of stony soils,
taking into account a correction for the soil stoniness. Variations in the water retention of the fine soil fraction and its
impact on both the soil water storage and the bottom boundary fluxes are studied as well. The deterministic water flow
model HYDRUS-1D is used in the study. The results indicate that the presence of rock fragments in a moderate-to-high
stony soil can decrease the soil water storage by 23% or more and affect the soil water dynamics. Simulated bottom
fluxes increased or decreased faster, and their maxima during the wet period were larger in the stony soil compared to the
non-stony one.
