26. Investigating the decrease ofgroundwater levels and the effect of fracture zone on recovery time: A case study of decrease in groundwater levels in a tunnel construction site in Vinsta, Stockholm
University essay from KTH/Hållbar utveckling, miljövetenskap och teknikAbstract : Groundwater is one of the main natural resources worldwide. Groundwater exists in aquifers below the earth surface and provides quantities of water for various purposes such as supply to households and businesses, public supply, drinking water supply, irrigation and agriculture. Sweden is also highly dependent on groundwater. READ MORE

27. Finite element analysis of cracking of concrete arch dams due to seasonal temperature variation
University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaperAbstract : Flera dammkonstruktioner i Norden utsätts för stora temperaturvariationer mellan sommar och vinter. I norra Sverige kan dammar vara utsatta för temperaturvariationer på upp emot 60–70 °C. Detta resulterar ofta i sprickbildning i betongen vilket medför utmaningar vid både utformning av nya dammar och underhåll av befintliga. READ MORE
