  2. 11. Permafrost Groundwater Dynamics : Modeling of vertical and lateral flows in the active layer across multiple scales

    Author : Alexandra Hamm; Andrew Frampton; Peter Kuhry; Jeffrey McKenzie; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; permafrost; climate change; numerical modeling; hydrogeology; groundwater; naturgeografi; Physical Geography;

    Abstract : Hydrological processes in the Arctic are profoundly influenced by the presence of permanently frozen ground, known as permafrost. Conversely, permafrost is greatly affected by hydrological changes resulting from climate change. READ MORE

  4. 12. Rainfall-Runoff Modelling Using Artificial Neural Networks (ANNs)

    Author : Aman Mohammad Kalteh; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydrogeology; geographical and geological engineering; Hydrogeologi; teknisk geologi; teknisk geografi; Self-organizing map; Feed-forward multilayer perceptron; Forecasting; Hydrological modelling; Missing values; Rainfall-runoff modelling; Estimation; Artificial neural networks;

    Abstract : Over the last decades or so, artificial neural networks (ANNs) have become one of the most promising tools for modelling hydrological processes such as rainfall-runoff processes. In most studies, ANNs have been demonstrated to show superior result compared to the traditional modelling approaches. READ MORE

  5. 13. Environmental impact of peat mining : Development of storm water treatment methods

    Author : Bjørn Kløve; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; geographical and geological engineering; Hydrogeology; drainage artificial floodplaines; phosphorus; suspended solids; nitrogen; erosion; peat mining; peak runoff controll; sedimentation; water treatment; water resources; hydrology; hydraulics; Hydrogeologi; teknisk geologi; teknisk geografi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi;

    Abstract : Drainage of peatlands increases the transport of suspended solids (SS) and the leaching of nutrients to downstream receiving waters. Increased settling of peat and eutrophication of lakes has been noted in many studies downstream from peat mines. READ MORE

  6. 14. Conceptual Runoff Models for Material Transport Estimations

    Author : Rikard Lidén; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; teknisk geologi; Hydrogeologi; geographical and geological engineering; Hydrogeology; Conceptual Rainfall-Runoff Modelling; Riverine Material Transport; teknisk geografi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi;

    Abstract : Catchment-scale material transport models are today important tools for water and environmental management. However, modelling of material transport is extremely complex due to the physical, chemical and biological processes involved. READ MORE

  7. 15. Groundwater occurrence and risk of pollution in a mountain watershed of Nicaragua

    Author : Alfredo Mendoza; Teknisk geologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; teknisk geologi; electrical resistivity; surface water; springs; Nicaragua; Hydrogeology; groundwater; teknisk geografi; geographical and geological engineering; Hydrogeologi;

    Abstract : Hydrogeological and geophysical methods were applied in the Río Artiguas watershed, a mountain basin located in central Nicaragua. This area is under environmental stress from anthropogenic activities like gold mining using mercury and waste disposal into the streams. READ MORE
