INFLUENCE OF SNOW COVER ON SOIL MOISTURE AND FROST DYNAMICS IN WINTER OF 2016–2017 IN CZECH REPUBLIC

Popis výsledku v původním jazyce

The timing and thickness of snow cover significantly affected the frost and soil moisture during the winter 2016/2017 in the Czech Republic. Snow began to fall at the beginning of winter in Bohemia, much later in Moravia. Very low January air temperatures caused the soil freezing. The maximum freezing depth was 0 to 20 cm in Bohemia, 20 to 80 cm in Moravia. Soil frosting had a very powerful effect on the infiltration of the melting snow and runoff. While the relatively thick frozen layer impeded infiltration in Moravia, in thin frozen layer in Bohemia, infiltration of meltwater was unimpeded. The measurement showed the rise in soil moisture in the soil profile of 0-100 cm at the end of the winter in Bohemia, on the contrary, the decrease in moisture in Moravia. Snow-cover characteristics significantly influenced soil moisture in the later growing season. These results clearly show that the changes in the timing and thickness of snow cover deposition can cause a dramatic reduction of frost depth and change in the soil water dynamics.
