WATER OUTFLOWS FROM SMALL AGRICULTURAL CATCHMENT IN WILAMOWICKIE FOOTHILLS

Keywords: precipitation, outflow layer, outflow coefficient, agricultural catchment
Abstract: In the years 1999–2001, research was conducted on the hydrological conditions of a small sub-mountain catchment of the Włosień stream situated in the Wieprz district in the Wilamowickie Foothills mezoregion. Almost 80% of the catchment is used for agriculture, and about 16% is covered by forests. With respect to precipitation, the research period may be considered as average because the mean annual precipitation was 912 mm which constituted 105% of the multi-annual mean. However, the individual years differed considerably in precipitation amounts: the first year was dry, the second year was normal, while the third year was very wet. The mean annual temperature of air, 9.0oC, was by 1.2oC higher than the multi-annual mean. Under such conditions, the annual depths of outflow layers ranged from 305 to 512 mm. On average, the outflow layer was deeper in the summer half-year due to the extremely large July outflows in the two last years of research. Despite the varied meteorological conditions, the outflow coefficients in individual years were almost identical and constituted 44% of the precipitation, on average.
