  1. 1. Groundwater Recharge in Crystalline Bedrock : Processes, Estimation, and Modelling

    Författare :Niclas Bockgård; Sven Halldin; Allan Rodhe; Auli Niemi; Lars O. Ericsson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hydrology; groundwater recharge; bedrock; crystalline rocks; tracers; CFC; surface loading; loading efficiency; barometric effect; heterogeneity; stochastic modelling; Hydrologi; Hydrology; Hydrologi;

    Sammanfattning : Kunskap om grundvattenbildningen är nödvändig för att man ska kunna förutsäga konsekvenserna av grundvattenuttag och underjordsbyggande. Grundvattenbildningen i berggrunden är dock svår att uppskatta. LÄS MER

  3. 2. Modern Artificial Recharge Plants : Combining chemical flocculation with aquifer recharge

    Författare :Kristofer Hägg; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Natural organic matter NOM ; Chemical flocculation; Ultrafiltration membrane; Disc filtration; Managed Aquifer Recharge;

    Sammanfattning : Water supply security is increasingly becoming a challenge worldwide. Surface waters, which are often used for drinking water production, have experienced an increase in natural organic matter (NOM) and frequency of algae blooms. Water quantity is also an issue due to increasing populations and potable water demand. LÄS MER

  4. 3. Floodwater harvesting for artificial recharge of groundwater - estimation and prediction for arid Iran

    Författare :Hossein Hashemi; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Artificial recharge; Groundwater modeling; Climate change; Spate irrigation; Arid area; FWS; GBP;

    Sammanfattning : Groundwater depletion in arid and semiarid areas is of increasing concern. Increasing water demand due to increasing population and climate change impacts have intensified the water shortage problems and put further stress especially on groundwater. LÄS MER

  5. 4. Artificial recharge of groundwater for public water supply : potential and limitations on boreal conditions

    Författare :Cristina Frycklund; KTH; []
    Nyckelord :;

    Sammanfattning : It is motivated by the intentions of Agenda 21 to findalternatives to the increasing dependence on chemical treatmentin the production of public water. Conventional waterworkscommonly include chemicals for removal of organic compounds,for reduction of corrosiveness and for disinfection. LÄS MER
