1. Permafrost Groundwater Dynamics : Modeling of vertical and lateral flows in the active layer across multiple scales
Sammanfattning : Hydrological processes in the Arctic are profoundly influenced by the presence of permanently frozen ground, known as permafrost. Conversely, permafrost is greatly affected by hydrological changes resulting from climate change. LÄS MER
2. Topographic Control of Groundwater Flow
Sammanfattning : Gravity is the main driving force for groundwater flow, and both landscape topography and geology distribute the effects of gravity on groundwater flow. The groundwater table defines the distribution of the potential energy of the water. LÄS MER
3. Linking water and permafrost dynamics
Sammanfattning : The extent and dynamics of permafrost are tightly linked to the distribution and movement of water in arctic landscapes. As the Arctic warms more rapidly than the global average, profound changes are expected in both permafrost and hydrology; however, much is still not known about the interactions between these two systems.

4. Uncertainties in modeling groundwater contamination
Sammanfattning : The scientific problem of nuclear waste disposal suffers from stronguncertainties arising both from its object (the system being studied being unknown) and also from its ambitious objectives (prediction of future events and their consequences). This work focuses on identifying, structuring and quantifying the main uncertainties involved in this field. LÄS MER
5. Towards sustainable water use in industry: a case study of the oil refinery industry in Kazakhstan
Sammanfattning : The concept of “Sustainable water use” (SWU) aims to assure three pillars of sustainability related to the water sector: the social, environmental, and economical. Industrial development, especially in developing countries, requires an adequate response, as industrial activities are recognized as one of the major sources of water pollution, what leads to deterioration of environmental safety and wellbeing of the society.
