Transforming Hydrographs in the Hillslope Subsurface

Popis výsledku v původním jazyce

To reveal and evaluate the mechanism of transforming rainfall into runoff in the region, where the subsurface flow plays a dominant role in the runoff formation, a hydrological monitoring has been set-up in the catchment Uhlířská. Beside a standard observation a hillslope transect was instrumented to control the flow dynamics in the soil profile. The subsurface outflow is recorded in the trench, the soil water suction is scanned by tensiometers. Within the soil profile the unsaturated regime prevails, nevertheless the soil keeps almost saturated. Simultaneous reaction of suction on a rainfall in soil horizons implies a rapid vertical flow. Local preferential paths are conducting infiltrating water at significantly variable rates when saturation is reached. Hydrological variables measured at the hillslope transect and the outflow from the catchment, are correlated. The outflow is dominantly controlled by soil moisture however the mechanism of its generation is not yet fully understood.
