Impact of Extreme Meteorological Phenomena on Soil Water Storage of Slovakia Typical Lowland Site

Change of the hydrologic cycle on the Earth is closely connected to the climate change caused by global warming of the atmosphere. The conditions in natural ecosystem in agricultural areas are changing. Both surface water resources and the soil water store react to the prospective changes. Some areas in Slovakia witness extreme maximum, minimum or are lack of precipitation much more frequently. The maximum of precipitation result in flooding and the minimum in excessive soil drying. In this paper actual soil water storage measured by neutron probe in period 1999-2004 at lowland region, specifically in locality Bodiky, is shown. Amount of water in unsaturated soil zone for soil layers 0-30 cm and 30-60 are assessed with regard to precipitation totals and temperature. Furthermore, the impact of climate change to the soil water storage is solved. Numerical simulation was calculated using mathematical model GLOBAL. Calculation of soil water storage has been determined for daily time step for 30-years reference period (1955-84) and for the time horizons 2010, 2030 2075.Climate parameters for time horizons 2010, 2030 and 2075 were modified for climate scenarios CCCM2000 and GISS98
