| Zusammenfassung |
| Forest hydrological models help us to understand the natural processes in forest. The forest
has huge active surface available for evaporation processes. The amount of precipitation
decreases after reaching the canopy. The throughfall arrives at the forest litter. The rainfall
retention of the litter is the litter interception. In this paper a hydrologic model was employed
for estimation of forest litter interception of a middle-aged sessile oak (Quercus
petraea) and beech (Fagus sylvatica) stand. The discussed forest litter interception is
an important element of the water balance of the forest and can be an important
parameter of the rainfall runoff models in forested area. The research catchment in
Hidegvíz Valley near Sopron provides valuable data for testing such kind of hydrologic
models. Antecedent water content and the storage capacity of the forest litter are
the main parameters of the model. The antecedent water content of the litter was
estimated by the daily precipitation and temperature data, collected in Hidegvíz Valley
research catchment in a three years long measurement period (2006-2008). The
measurements were done by own developed instrument, where the undisturbed forest
litter samples are enclosed in frames and it was measured on stationary place in
every time step. Our model estimation for litter interception was 5–7% of gross
precipitation.
