ABSTRACT:
The paper presents the results of the researches carried out at the catchment of water pond number one, located at Wielosławice Forestry of Siemianice Experimental Farm. The researches were carried out in three hydrological years 2002/2003, 2003/2004 i 2009/2010 of a different precipitation sums. The area of investigated catchment of pond number one is about 7,5 ha and its forestation totals 100 % and it is situated in a part of Niesób catchment - left-side tributary of Prosna River. Fresh habitats and proper podzols consist of loamy sand texture predominant in soil cover at the area of investigated catchment. Pond No 1, which area is about 0,35 ha and average depth is about 1,4 m, is a typical natural melt pond with gentle slopes. The results confirmed that water storage in pond No1 restored, particularly in winter half-years, dependently of meteorological condition courses. The researches indicate the dominant role of income part of water balance at pond No 1 catchment had precipitation sums. The sums fluctuated from 650 mm (2002/2003) to 992 (2009/2010) in analyzed hydrological years. Evaporation from pond surface which was from 408 mm (2009/2010) to 835 mm (2002/2003) was the dominant factor of outgoing part of water balance. Outflow from the pond to neighboring areas had significant participation – about 44% of precipitation, in water balance in wet 2009/2010 hydrological year.
