1. 6. Aerosol deposition to coastal forests: a wind tunnel approach

   Författare :Ausra Reinap; Bo L.B. Wiman; Birgitta Svenningsson; Bo Bergbäck; Lise Lotte Sørensen; Linnéuniversitetet; []
   Nyckelord :NaCl aerosol; dry deposition; climate change; coastal-zone forest; Quercus robur; wind tunnel; edge effect; NATURAL SCIENCES; NATURVETENSKAP; Miljövetenskap; Environmental Science;

   Sammanfattning : Aerodynamically rough surfaces of forests provide for efficient air/ canopy exchange of mass, heat and momentum. In that context, the effects of forest edges come into focus, and therefore, coastal-zone forests constitute aparticular concern. LÄS MER

   Sammanfattning : The thesis aims at deconstructing the sustainable tourism paradigm: can tourism be "a global strategy for sustainable development", as the tourist industry claims? And will developing countries in particular profit from tourism development?To most international organizations and institutions (from the World Wide Fund for Nature to The World Bank), tourism, if carefully managed, is a positive, sustainable development tool. However, the research presented in this thesis exposes this view as unrealistically optimistic for at least three reasons: first of all, global environmental change caused by tourism has never been investigated and integrated with the discourse on sustainable tourism development.

4. 8. Simulations of Coastal Atmospheric Dynamics and Transport Processes

   Författare :Ragothaman Sundararajan; Dimitris Melas; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; coastal atmosphere; dynamics; transport; Lagrangian particle dispersion model; mesoscale model; turbulence; Geovetenskap; Earth sciences; Geovetenskap; Meteorology; meteorologi;

   Sammanfattning : The marine atmosphere can be highly variable in space and time, and the coastal terrain plays a crucial role in influencing its properties. These, in turn, determine the atmospheric transport in the coastal zone. LÄS MER

7. 10. Groundwater-Seawater Interactions : Seawater Intrusion, Submarine Groundwater Discharge and Temporal Variability and Randomness Effects

   Författare :Carmen Prieto; Georgia Destouni; Vassilios Kaleris; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydraulic engineering; Seawater intrusion; submarine groundwater discharge; coastal groundwater management; coastal zone management; temporal variability; temporal randomness; Vattenteknik; Water engineering; Vattenteknik;

   Sammanfattning : Fresh groundwater quality and availability in coastal areas is affected by seawater intrusion into coastal aquifers, and coastal water quality and ecosystem status may be significantly affected by groundwater pollutants that are transported into coastal waters by submarine groundwater dis-charge (SGD). This thesis uses an overall regional perspective for investigating: i) seawater intru-sion and its possible control in sustainable coastal groundwater management; ii) SGD and its relevant quantification as one interacting part among the diverse main regional pathways of freshwater and tracer/pollutant inputs from land to sea; and iii) the integrated system functioning of both i) and ii) as main components of the same coastal groundwater system.
