Abstract


GEOLOGY OF THE AQUIFER AREAS OF AN INDUCED INFILTRATION INTAKE IN THE CITY OF WROCŁAW

Abstract. The paper presents the results of geological research in the area of induced infiltration aquifer in the city of Wrocław. Based on drilling and geophysical prospection (GPR) data, a 3D model of the aquifer has been developed, showing the architecture of the aquifer-forming sediments. The best hydrogeological and spatial-related parameters are displayed by gravels directly overlying the impermeable basement represented most likely by pre-Odra River sediments and filling fossil valley structures. A geological-physiographic map, compiled based on the LiDAR digital elevation model, revealed two youngest sedimentary valley systems related to the recent channels of the Odra and Oława rivers. The structure of these deposits is typical of meandering river cyclothems. The use of its anisotropy can significantly improve the efficiency of infiltration of surface water into the water-bearing and conducting gravels that constitute the main usable aquifer.
