INFILTRATION - still mysterious?

Popis výsledku v původním jazyce

Water infiltration into soil is an important component of hydrological cycle affecting soil moisture and ground water recharge, as well as surface runoff generation during rainfall events. Soil profile ability to intake water during a rainfall event is usually evaluated using soil potential infiltration (soil infiltrability), i.e. infiltration under unlimited water supply. This is commonly obtained experimentally with a standard ponded infiltration experiment. The number of obstacles are biasing the results of experiments, most importantly disturbance of soil around ring walls during ring insertion, complicated role of vegetation cover, and representativeness of determined values for an experimental site. Present study was designed to assess spatial and temporal variability of the soil infiltrability. The results highlight shortcomings of in-situ ponded infiltration tests.
