  1. 1. 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; 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

  2. 2. Green Urban Drainage Infrastructure : Hydrology and Modelling of Grass Swales

    Author : Hendrik Rujner; Maria Viklander; Günther Leonhardt; Jiri Marsalek; Barraud Sylvie; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Abstract : The management of urban runoff has evolved along with the advancement of understanding of runoff environmental impacts. Besides the impacts on water quality in the receiving waters, the impacts on the urban hydrologic regime include reduced infiltration by the sealing of pervious land, reduced evapotranspiration by removal of vegetation, and the resulting increase of stormwater runoff peaks and volumes causing flooding, and ultimately degradation of receiving waters.

  3. 3. Environmental management of water systems under uncertainty

    Author : Christian Baresel; Georgia Destouni; Vladimir Cvetkovic; Keith Beven Beven; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Water Resources Engineering; Water engineering; Vattenteknik;

    Abstract : Hydrological drainage/river basins constitute highly heterogeneous systems of coupled natural and anthropogenic water and pollutant flows across political, national and international boundaries. These flows need to be appropriately understood, quantified and communicated to stakeholders, in order to appropriately guide environmental water system management. READ MORE

  4. 4. Biogeochemical Processes in Denitrifying Woodchip Bioreactors and their Application in the Mining Industry

    Author : Albin Nordström; Roger Herbert; Fritjof Fagerlund; Gunno Renman; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; water treatment; mine drainage; nitrate; nitrous oxide; DNRA; fermentation; syntrophy; temperature; kväverening; gruvvatten; nitrat; lustgas; DNRA; fermentation; syntrofi; temperatur; Hydrology; Hydrologi;

    Abstract : This thesis evaluates passive denitrifying woodchip bioreactors (DWBs) for the removal of nitrate (NO3-) in neutral pH mine drainage, where water is passed through a carbon-rich porous matrix (e.g. woodchips) for the reduction of NO3- to nitrogen gas. READ MORE

  5. 5. Basin-scale change in water availability and water quality under intensified irrigated agriculture

    Author : Rebecka Törnqvist; Jerker Jarsjö; Marcel van der Perk; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Irrigation; Hydrology; Land-use change; Basin-scale; Central Asia; Aral Sea; Semi-arid; Return flow; Water saving; Health risk; Water quality; Surface water; Groundwater; Nitrogen; Attenuation; Recirculation; Climate change; Physical Geography; naturgeografi;

    Abstract : Changes in land use and water use can greatly impact the cycling of water and water-borne substances. Increased redistribution of river water to irrigated fields can cause enhanced evapotranspiration and decreased river discharge. READ MORE
