1. High levels of nickel from sulphide soil in Umeå's raw water : Modeling of groundwater flow and mass transport in Forslunda aquifer
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : The raw water in some of Umeå's abstraction wells has shown high nickel levels for more than a decade. The cause has not been determined but there is an investigation from 2010 where the results indicate sulphide clay found adjacent to two basins used for artificial infiltration. LÄS MER
2. THE FIRST ACTIVE ACID SULFATE SOIL FOUND OUTSIDE THE BALTIC BASIN, IN VISKA VALLEY WEST COAST OF SWEDEN
Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaperSammanfattning : Acid sulfate (AS) soils are naturally formed but are responsible for environmental problem due to its low pH. Drainage of active AS soils can lead to mobilization of harmful metals and a severe pH drop in nearby aquatic environments, which in turn may harm the ecological conditions. LÄS MER
3. Soil Improvement method by Mass Stabilization : Settlement analysis in stabilized sulfide soil
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : Mass stabilization is not a common soil improvement method in Sweden, and even less so in sulfide soils. Previous research indicates that a linear elastic material model is suitable for settlements in stabilized sulfide soil. A construction project in the northern part of Sweden applied mass stabilization in sulfide soil. LÄS MER
4. Long-Term Impact of Drought on AcidSulfate Soil Leaching, a Study of NineCatchment Areas in Sweden and Finland
Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapsläraSammanfattning : Sediments rich in sulfide were deposited in the Littorina sea in an environment that was shallow, anoxic,and reductive. The sediments were brought above sea level by isostatic uplift and can now be foundalong the coast of the Baltic sea. LÄS MER
5. Grundläggning av ny bro på postglacial lera i Uppsala
Kandidat-uppsats, Malmö universitet/Fakulteten för teknik och samhälle (TS)Sammanfattning : I detta examensarbete har en geoteknisk utredning utförts för att bedöma ifall grundläggning aven bro över Fyrisån i Uppsala kan utföras på enklaste sätt, genom plattgrundläggning. Arbetethar grundats på att undersöka hur grundläggningen styrs av den postglaciala lerans tekniskaegenskaper. LÄS MER
