1. Salthaltigt grundvatten i Rådaås grundvattentäkt : en studie av förekomst, ursprung och hur brunnsdrift påverkar halten i uttagsvattnet
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapsläraSammanfattning : Lidköpings kommun i Västra Götalands län tar ut en del av sitt råvatten till dricksvattenproduktion från grundvattenmagasinet Rådaås. Det görs genom tre olika uttagsbrunnar (Brunn 1, Brunn 2 och Brunn 3) som körs en i taget. LÄS MER
2. Timber pile-supported road embankment : Numerical and analytical analysis of field monitoring project E4 Råneå
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/GeoteknologiSammanfattning : The previous E4 Råneå road embankment was prone to flooding. Risk of flooding in combination with settlements of the road due to the weak underlying sulphide soil was problematic. The Swedish Transportation Administration improved the length section E4 Råneå by rebuilding the road using the method light embankment piling. LÄS MER
3. Evaluation of long-term performance of sodium silicate grouted in embankment dams
Master-uppsats, KTH/Jord- och bergmekanikSammanfattning : Embankment dams is the most common type of dams in operation inSweden today. Due to the nature of embankment dams, seepage throughthem will always occur. If the seepage velocity exceeds a critical velocity,internal erosion is initiated, which could lead to damage in form of pipingand sinkholes. LÄS MER
4. An alarm system for pore pressure measurements in the foundation ofconcrete dams : a case study of Storfinnforsen buttress dam
Master-uppsats, KTH/Jord- och bergmekanikSammanfattning : Concrete buttress dams are relatively light structures and less demandingon foundations; because of that, they may have problems with upliftforces and horizontal joints in the area of the dam´s foundation maypresent a failure mode through sliding. The Storfinnforsen dam, thelargest concrete dam in Sweden, had its foundation studied recently andthe discovery of sub-horizontal joints in the bedrock led to the necessityof having the safety of the dam foundation to sliding assessed.

5. Groundwater Chemistry in the Amazon Rainforest
Master-uppsats, Linköpings universitet/Tema MiljöförändringSammanfattning : Groundwater chemistry is highly variable and dependent on environmental conditions, and it is not entirely understood how all these factors contribute to groundwater chemistry. This study aims to examine some of the factors that contribute to groundwater heterogeneity in the Amazon Rainforest. LÄS MER
