Abstract
An aquifer in a horseshoe bend of the Weser river was investigated regarding the processes of the river water infiltration. The geology and geometry of the aquifer was ascertained by means of numerous borings. The hydraulic situation before and after infiltration was determined by water table maps. The intrusion of a salt-freshwater lens could be reconstructed from the beginning of infiltration until ten years later by means of previous results of chemical analysis. By new chemical analysis it was proved that river water infiltrates into the aquifer. Additionally it was established that the relatively high concentration of chloride is reduced during the passage of the groundwater both by mixing with recharged groundwater and by adsorption of the ground. Furthermore temperature measurements in the groundwater at selected stations confirm qualitatively the river water infiltration into the polder.
