Badania zmienności i zależności temperatury wód podziemnych od wód rzecznych na ujęciach infiltracyjnych

The paper presents the results ofmeasurements of groundwater and surface water temperature in the area of the Krajkowo water intake. The influence of extreme natural phenomena on Warta River in Krajkowo on the conditions of exploitation of the shore barrier and the radius well are shown. Changes in the velocity of water flow from the Warta River to the well of the shore barrier has been noticed. Such results shown an important role of protective monitoring of a water capture.
