ABSTRACT
The paper presents the results of the researches carried out in the catchments of pond No 1 and No 6. The ponds are located in Siemianice Experimental Farm, belonging to “Lasy Rychtalskie” Promotional Forest Complex, in Wielisławice (pond No 1) and Laski forestry (pond No 6). The researches were carried out in two hydrological years 2010/2011 and 2012/2013. The years had different precipitation. The area of catchment of pond No 1 is about 7.5 ha and its forestation totals 100%. Whereas catchment area of pond No 6 is about 37 ha. The forestation of this pond is about 40% and the rest are arable areas. The analyzed pond No 1 and 6, have mild scarps, and they are natural pond melting out. The area of pond No 1 is 0.13 ha, whereas pond No 6 is 0.35 ha, and averages depths of both ponds are 1.0 m and 1.4 m. The results confirmed a connection between water in ponds and groundwater in neighboring areas. In some periods water of ponds supply surrounding areas and in some periods on the contrary – groundwater supply water in ponds. Correlation coefficient (from 0.43 to 0.96) calculated for relation between water levels in ponds and groundwater were statistically significant for the level α=0.01 in analyzed hydrological years.
