Zmiany stanów i temperatury wód podziemnych w wybranych zlewniach Karkonoszy

Abstract

Changes in the groundwater level and temperature in selected catchments of the Karkonosze Mts.A b s t r a c t . The paper presents the results of groundwater level and temperature monitoring in the main porous-fissured aquifer occurring in selected catchments of the Karkonosze Mts. The analysis was based on the results of observations carried out in two catchments (Łomnica and Wrzosówka rivers) of the Karkonosze National Park during the period of 2014–2016, where 6 piezometers at depths of 4.80 to 13.45 m were installed. Groundwater monitoring is carried out in an elevation transect, in the range from about 600 to almost 1090 m a.s.l. Significant elevations of the water level were observed after rainfall and melting recharge in the spring, and long regression periods in the summer-autumn season.
