1. The weakest link : Governing the risk of floods and dam failure in Sweden
Abstract : The effects of climate change are already being felt today, and future effects, which will be determined by the readiness and resolve of today’s world leaders, are fraught with high levels of complexity, uncertainty, ambiguity, and transboundary effects – characteristics of systemic risk. Since climate change is seen as a threat multiplier, the risks that might be impacted by climate change, such as floods and dam failure, will be affected by systemic risk characteristics as well.

2. Toward Realistic Failure Evaluations for Concrete Buttress Dams
Abstract : Concrete dams, complex structures supporting massive loads, have traditionally been assessed using simplified 2D analytical stability analyses based on the rigid body assumption. Previous studies have shown that 3D behavior, such as the interaction between the monoliths and the valley's geology, can greatly impact the load-bearing capacity of gravity dams but remains largely unexplored in buttress dams.

3. Reliability-based Assessment of Concrete Dam Stability
Abstract : Risk management is increasingly used in dam safety and includes risk analysis, risk evaluation and risk reduction. Structural Reliability Analysis (SRA) is a probabilistic methodology that may be used in the risk assessment process. READ MORE

4. Dam safety in a hydrological perspective-Case study of the historical water system of Sala Silver Mine
Abstract : The old water system in Sala, formerly belonging to thesilver mine, is analysed with regard to dam safety focusing onthe hydrological aspects. The hydrological safety of the riskclass I dams in the area, built in the 16th century, is notconsidered adequate according to the Swedish guidelines fordesign flood determination. READ MORE

5. Numerical analyses of stability of a gradually raised tailings dam
Abstract : Numerical analyses are presented in this thesis to address potential stability problems that may occur during gradual raisings and under seismic loading conditions of Aitik tailings dam in northern Sweden. The dam is mainly raised using upstream construction method. It is planned to raise the dam gradually in several stages. READ MORE
