Wielkość infiltracji w strefie aeracji rozwiniętej na skałach krystalicznych Sudetów i Przedgórza Sudeckiego
Abstract
Infiltration rate within vadose zone developed on crystalline rocks in the Sudety Mountains and their Foreland.
A b s t r a c t. The paper presents results of studies on groundwater recharge in the Sudety Mountains and their Foreland in hydrological years 2004–2006. Five locations were selected for detailed study with the aid of lysimeters installed permanently in the ground. The recorded infiltration was compared with precipitation and other hitherto gathered data. Precipitation data for the period from January 2004 to July 2005 were provided by the Institute of Meteorology and Water Management. The studies showed large variability of infiltration time series and water infiltration mainly in colder half of the year (November to April) in some of sampling points and rates of infiltration more or less equal throughout the whole year in other points. The obtained data show infiltration values to be higher in the Sudety Mountains than in their Foreland. The studies indicate decisive influence of climatic factors such as precipitation and mean annual temperature, on infiltration rates in this region.
