Subsurface Outflow Episodes on the Hillslope Cause by Snowmelt

Popis výsledku v původním jazyce

In the experimental watershed Uhlirska,, Czech Republic, hydrological research with the focus to the processes in the subsurface is performed. Data collection of the water regime and the subsurface flow caused by the snowmelt is performed since 2000. Inthe constructed subsurface trench the shallow subsurface runoff intensity is measured. The water saturation of the soil profile is controlled by tensiometers. The typical soil profile at the site is highly heterogeneous, formed by 0.8-1.2 m of Cambisols.Due to the highly permeable topsoil and preferential flow in the whole soil profile, no overland flow occurs. Subsurface outflow is caused by the snowmelt of a different duration and magnitude due to the combination of the air temperature rise, presentsnow height and its water content and rainfall accelerating the processes of snow thawing. Soil profile during snowmelt is mostly saturated, it often fluctuates as a response to temperature cycle of the daily thawing and freezing.
