2. 1. Water in roads: Flow paths and pollutant spread

   Author : Hedi Rasul; B. Olofsson; Helen Kristine French; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; De-icing salt; Road; Tracer test; ERT; Water content; Road pollutants; Flow pathways; Land and Water Resources Engineering; Mark- och vattenteknik;

   Abstract : For better road construction and maintenance while minimising damage to the environment and groundwater, it is essential to monitor and model hydrological impacts on roads and consider pollution of groundwater. Water content in unbound material in road layers changes continuously and water flow usually occurs along pathways that are the main corridors for pollutant spread to groundwater. READ MORE

4. 2. More Water, Less Grass? : An assessment of resource degradation and stakeholders’ perceptions of environmental change in Ombuga Grassland, Northern Namibia

   Author : Patrik Klintenberg; Carl Christiansson; Wolter Arnberg; Peter Schlyter; Stein W. Bie; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Environmental monitoring; semi-arid; pastoralism; rural water supply; indicators; local knowledge; vegetation survey; satellite remote sensing; Physical geography; Naturgeografi; geografi med naturgeografisk inriktning; Physical Geography;

   Abstract : The objectives of this thesis are to assess: to what degree have natural resources deteriorated in a grazing area in northern Namibia, how do perceptions of environmental change held by local stakeholders there, correspond to scientific assessments, and how do these relate to national estimates? Analysis of the process of developing national indicators for monitoring of land degradation concluded that specific indicators should be developed on national level, and in some instances even on local level as there are no universal causes of land degradation. According to farmers overgrazing and low rainfall since the early 1990s cause negative environmental changes in the study area, partly confirming findings from national monitoring. READ MORE

5. 3. Linking water and permafrost dynamics

   Author : Ylva Sjöberg; Steve Lyon; Andrew Frampton; Britta Sannel; Georgia Destouni; Michelle Walvoord; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; permafrost; hydrology; arctic; modeling; streamflow; geophysical measurements; ground thermal dynamics; groundwater; Physical Geography; naturgeografi;

   Abstract : The extent and dynamics of permafrost are tightly linked to the distribution and movement of water in arctic landscapes. As the Arctic warms more rapidly than the global average, profound changes are expected in both permafrost and hydrology; however, much is still not known about the interactions between these two systems.

6. 4. Condensation irrigation : simulations of heat and mass transfer

   Author : Jenny Lindblom; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

   Abstract : There is a growing water demand in the world. Along with the deterioration of existing water supplies, the escalating world population leads to the assumption that two out of three people will lack sufficient freshwater by the year 2025. READ MORE

7. 5. Reduction of prime energy consumption in the Middle East by GSHP systems

   Author : Mohamad Kharseh; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

   Abstract : The global energy consumption, which increased ~84% during last thirty years, exceeded 1.4.1011 MWh in 2008. It is projected to increase another ~39% until 2030. READ MORE
