  2. 16. 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 : 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

  4. 17. On the scope and assessment of pesticides in groundwater in Skåne, Sweden

    Author : Maria Åkesson; Kvartärgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; groundwater; pesticides; Sweden; Skåne; environmental tracers;

    Abstract : Pesticides are known to occur in groundwater worldwide. However, long-term pollution concerns and cause-effect relationships for specific regions remain limited. READ MORE

  5. 18. 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

  6. 19. EstimatingChloride concentration in surface water and groundwater duet to deicing salt application

    Author : Eva-Lotta Thunqvist; KTH; []
    Keywords : road; deicing salt; monitoring; chloride; catchment area; river basin; simulation; GIS; groundwater; surface water;

    Abstract : A road in operation along with its traffic can pose aserious pollutant threat to groundwater and surface water inits vicinity. Examples of pollutants are metals from thecorrosion of vehicles, rails and poles and the wear of roadsurfaces and tyres; hydrocarbons from the wear of roadsurfaces, tyres, exhausts, oils; sodium chloride from roadsalt; and hazardous goods discharged in accidents.

  7. 20. Solute transport in the integrated soil-groundwater system

    Author : Eva Simic; KTH; []
    Keywords : solute transport; groundwater transport; integrated soil.groundwater system;

    Abstract : A Lagrangian stochastic travel time approach has been usedfor investigating dominant process impacts on (non-reactive andreactive) solute transport in the integrated soil-groundwatersystem. A first step has also been taken to extending thisLagrangian stochastic travel time approach to integrate thesoil-groundwater-stream transport through a catchment. READ MORE
