1. Modeling Solute Transport in Fractured Rocks-Role of Heterogeneity, Stagnant Water Zone and Decay Chain
Abstract : A model is developed to describe solute transport and retention in fractured rocks. It accounts for the fact that solutes not only can diffuse directly from the flowing channel into the adjacent rock matrix composed of different geological layers but can also at first diffuse into the stagnant water zone occupied in part of the fracture and then from there into the rock matrix adjacent to it.

2. Metals released from mine waste deposits : Redistribution and fluxes through geological barriers
Abstract : The redistribution of metals from point sources (sulphidic mine waste) is presented in this thesis. The impact on surface water systems is determined from water quality and sediment data. It is generally found that lakes act as sinks for the metals, to a different extent for eachmetal. READ MORE

3. Solute transport through fractured rocks : the influence of geological heterogeneities and stagnant water zones
Abstract : To describe reactive solute transport and retardation through fractured rocks, three models are developed in the study with different focuses on the physical processes involved and different simplifications of the basic building block of the heterogeneous rock domain. The first model evaluates the effects of the heterogeneity of the rock matrix and the stagnant water zones in part of the fracture plane. READ MORE

4. Developing geochemical and mineralogical proxies for the correlation of paleotsunami layers
Abstract : The catastrophic Indian Ocean tsunami of December 2004 raised urgent questions about the paleotsunami history in the region. Numerous studies have since been conducted to gain better understanding of the magnitude, frequency and impact of past tsunamis, especially around the coasts of the Indian Ocean. READ MORE

5. Modeling of geohydrological processes in geological CO2 storage – with focus on residual trapping
Abstract : Geological storage of carbon dioxide (CO2) in deep saline aquifers is one approach to mitigate release from large point sources to the atmosphere. Understanding of in-situ processes providing trapping is important to the development of realistic models and the planning of future storage projects. READ MORE
