  4. 4. Evaluating locations for subsurface dams : Case study on Storsudret, Gotland

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik; KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Karl Engström; Maximilian Skoglund Lartell; [2020]
    Keywords : Subsurface dams; MIKE SHE; groundwater; groundwater modelling; water resource management; resistivity measurements; hydrogeology; Grundvattendammar; MIKE SHE; grundvatten; hydrogeologi; grundvattenmodellering; vattenresurshantering; resistivitetsmätningar; hydrogeologi;

    Abstract : Due to precipitation poor winters and springs and over-exploitation of groundwater reserves during the summer months as a consequence of tourism, the island of Gotland has experienced fresh water shortages during recent years which has led to harsh restrictions in the use of municipal water. In order to find a solution to the islands fresh water problems, the region of Gotland and the Swedish Environmental Institute (IVL) have initiated a project in which the southernmost part of Gotland, Storsudret, will be used as a test site for new methods of sustainable freshwater storage and extraction methods.
