1. Modelling of Fluid Flow and Contaminant Transport in Fractured Rock : Case Study
University essay from KTH/Hållbar utveckling, miljövetenskap och teknikAbstract : Drinking water contamination is a big concern in Sweden and is commonly traced back to being waste from former manufacturing industrial sites. Pollutants in the topsoil can be remediated by several techniques, such as decontamination or excavation but the toxins already enclosed in the bedrock cannot be treated the same and is harder to track possible contaminant pathways.

2. Epidotization as an Effect of Fluid Rock Interaction, Recorded by a Granitoid From Hågadalen, Uppsala
University essay from Uppsala universitet/Mineralogi, petrologi och tektonikAbstract : A common driving mechanism of metamorphic processes, from which secondary mineralizations and structures develop in a protolith, is known to be a change of the immediate P-T environment that a rock resides in. A factor in this process, which is poorly understood, however, is how the presence of metamorphic fluids in a system, influences the alteration of primary igneous rocks. READ MORE

3. Feasibility of Enhanced Geothermal Systems in the Precambrian crystalline basement in SW Scania, Sweden
University essay from Lunds universitet/Geologiska institutionenAbstract : The ability to evaluate the geothermal potential at a depth of five to six kilometres in the crystalline bedrock is crucial for the EGS-technology to be utilized in the future. This work focuses primarily on presenting expected geological conditions at great depths in southwestern Scania. The study is based on information from E. READ MORE

4. Application of Dynamic Grouting to Improve the Grout Spread Using Varying Aperture Long Slot (VALS) : AN EXPERIMENTAL STUDY
University essay from KTH/Jord- och bergmekanik; KTH/ByggvetenskapAbstract : In the past centuries, grouting has been one of the most common techniques in geotechnical engineering to strengthen and seal underground structures. Concerning increasing demands for tightness and cost efficiency, cement-based grout has been one the most frequent used materials. READ MORE

5. Significance of Fracture Patterns in a Rock Mass during Excavation by Blasting in Bandhagen, Sweden
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : When excavating a rock wall by blasting, pre-existing structures in the rock has a strong impact on the stability of the wall. For excavation in Bandhagen in Stockholm, the nature and orientation of the pre-existing geological features, namely fractures, were not taken into consideration before excavation begun. READ MORE
