Wind drifted snow influence on the water balance in the catchment “Modrý potok”, the Giant Mountains, Czech Republic
Dvořák, I.J. ; Tesař, Miroslav ; Harčarik, J.
There are very specific components of the water balance in the mountain headwater regions. Beside the point of cloud- and fog-water deposition it is mainly accumulation of water in the snow cover drifted in the watershed by the wind. To get more realistic data, two digital models using cinematic carrier phase-based GPS measurements were developed: a model for snow surface data and the one for the underlying snow free ground surface. These two models have identified snow depths. The objective of this study is to highlight water storage in the snow-beds and show the GPS cinematic measurements as a contribution to best insight the snow accumulating and melting processes in the Modrý potok basin in the Giant Mts.
