1. Natura 2000-områdens roll i omprövningen av vattenkraftens miljötillstånd
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Miljö- och energisystemSammanfattning : Vattenkraften utgör ungefär 45 % av Sveriges elproduktion och har varit en stabil energikälla med lågt koldioxidutsläpp under lång tid. Med ett allt större inslag av intermittenta energislag i elsystemet, fyller vattenkraften också en viktig funktion med sin reglerförmåga för balansering. LÄS MER
2. An Idea of Land : Hydroelectric Dams lying in the middle of the Sámi of Sweden and Three Affiliated Tribes in the United States.
Master-uppsats, Uppsala universitet/Historiska institutionenSammanfattning : In this study a comparative approach between both the Sámi of northern Sweden and the Three Affiliated Tribes of North Dakota in relation to the constructions of the Letsi Reservoir and Garrison Dams will be given. The comparison will help create an understanding of what kinds of impacts they had to a number of factors. LÄS MER
3. Geomorphic change along the Rönne river : Effects caused by dams
Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : Many rivers can shape their path through the landscape with erosion and deposition where the riverbed and riverbanks both shape the direction and energy of the flow. The river flow can erode the riverbanks and create meanders which is when the river creates bends in its path that become increasingly curved. LÄS MER
4. Headfirst into shallow water - Wetland restoration and its contribution to the Habitats Directive
Master-uppsats, Uppsala universitet/Växtekologi och evolution; Uppsala universitet/Institutionen för biologisk grundutbildningSammanfattning : Located in the borderland between aquatic and terrestrial environments, the wetlands cover a wide spectrum of habitats and enable living standards for a great variety of organisms. Although important habitats, a great extent of the original wetlands have disappeared in Europe and Sweden due to anthropogenic disturbances. LÄS MER
5. Sensitivity of Norway Spruce (Picea abies) to inundation.
Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : Alteration of river flow regimes due to dams result in modifications of riparian ecosystem, with impacts on vegetation, landforms, and habitats. A key characteristic that differentiates riparian zones from adjacent aquatic and terrestrial environments is the event of periodic flooding and water logging. LÄS MER
