The catchment with an area of 224.9 km2 is located south-west of Lublin. The characteristics of the groundwaters and runoff were determined based on hydrological and hydrogeological materials of the Department of Hydrology of the Maria Curie-Skłodowska University (UMCS). Mean runoff in the period from 2010 to 2016 amounted to 125.7 mm, precipitation 629.4 mm, and evapotranspi-ration 503.7 mm. A strong relationship was determined between the rhythm of runoff and ground-water level fluctuations. The contribution of groundwater supply in total runoff equalled 81.5%.}, type={Artykuły / Articles}, title={Hydrological characteristics of the Krężniczanka River}, URL={http://czasopisma.pan.pl/Content/107241/PDF-MASTER/Michalczyk.pdf}, keywords={groundwaters, runoff, water balance, the Krężniczanka River, Lublin Upland}, }
