1. 21. Arctic Water System Change and its Interactions with Permafrost and Ecosystem Changes

   Författare :Johanna Mård Karlsson; Georgia Destouni; Daqing Yang; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Arctic; climate change; monitoring; ecosystem shifts; hydrology; hydro-climatic change; permafrost; Physical Geography; naturgeografi;

   Sammanfattning : Climate change and various changes in the landscape itself, such as permafrost thaw, may trigger and mediate substantial changes in the inland water system of the Arctic. Many climate change responses in the Arctic landscape and ecosystems are then related to alterations in the hydrological system. LÄS MER

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

   Författare :Rebecka Törnqvist; Jerker Jarsjö; Marcel van der Perk; Stockholms universitet; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

4. 23. The influence by point sources on carbon, nitrogen and metals in two sedimentary environments

   Författare :Hanna Bohlin; Nils Holm; Carl-Magnus Mörth; Gunnar Jacks; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Geovetenskap;

   Sammanfattning : Sediments in two aquatic environments have been investigated. Both are anthropogenically affected and polluted. The focus has been on stable carbon and nitrogen isotopes, C/N ratios, and heavy metals. The first site is Höggarnsfjärden Bay in the inner parts of the Stockholm Archipelago, Sweden, where a garbage dump releases treated leach water. LÄS MER

5. 24. Groundwater Vulnerability Assessment to pollution in Different Soil and Rock Materials

   Författare :Twana Abdullah; Nadhir Al-Ansari; Sven Knutsson; Jan Laue; Sabbar Alqaisi; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Groundwater; Vulnerability; DRASTIC; VLDA; Modification; Soil Mechanics; Geoteknik;

   Sammanfattning : The augmentation of human population regularly corresponds with change in the land cover, including expansion of urban areas, which imposes increasing the available amount of domestic and drinking water. The study area, Halabja-Saidsadiq Basin, is situated in the Northeast of Iraq and is one of the major groundwater sources of the region. LÄS MER

7. 25. Municipal wastewater treatment by microsieving, microfiltration and forward osmosis : Concepts and potentials

   Författare :TOBIAS HEY; Avdelningen för kemiteknik; []
   Nyckelord :Direct membrane filtration; electricity; energy; forward osmosis; microfiltration; microsieving; municipal wastewater treatment; treatment concept; Direct membrane filtration; Electricity; Energy; Forward osmosis; Microfiltration; Microsieving; Municipal wastewater treatment; Treatment concept;

   Sammanfattning : Conventional wastewater treatment plants are designed for treating manmade wastewater (e.g., from households and industries) and to protect the environment (e.g. LÄS MER
