Groundwater recharge/discharge patterns and groundwater–surface water interactions in a sedimentary aquifer along the River Kitinen in Sodankylä, northern Finland
Areas of groundwater–surface water interaction in riverbanks and open mires are important habitats for groundwater-dependent species. In order to preserve these ecosystems, the planning and development of mining operations on such locations require a fundamental understanding of the groundwater disc...
