The possibility to implement artificial recharge at Kristianstadsslätten in south of Sweden / Möjligheter med konstgjord grundvattenbildning i Kristianstadsslätten i södra Sverige
The Kristianstadsslätten plain is located in south of Sweden and holds one of the largest aquifers in the country. Kristianstadsslätten has been of greatest importance for groundwater abstraction and an ever-increasing desire to intensify the groundwater abstraction exists. The aim of this paper is to determine if it is possible to implement artificial recharge at one or all three major eskers located within Kristianstadsslätten to increase the recharge and in turn the groundwater resource. Previously performed research and literature of Kristianstadsslätten have systematically been studied. Eskers, borehole logs and different maps were studied. Data was further derived and the volume of infiltration of different scenarios was estimated together with the flowrate of the different geological layers within the eskers by using Darcy’s law. The observations and calculations show that the flowrate of each of the geological layers had a higher potential flowrate than the total volume of infiltration within a suggested artificial recharge plant. Observations of the borehole logs and leakage and pressure maps show that there are potential areas where high permeable material together with high recharge and high vertical leakage are encountered. Both Rinkaby-Oppmannaåsen esker and Gualövåsen esker have the greatest potential areas of high infiltration. Even if it is considered that further research is necessary, mainly due to the lack of knowledge of the unconsolidated layer, the given results show that it is possible to implement artificial recharge.
