1. Significance of transport dynamics on concentration statistics and expected mass fraction based risk assessment in the subsurface
Sammanfattning : This thesis relies on a Langrangian framework used for conservative tracer transport simulations through 2-D heterogeneous porous media. Conducted numerical simulations enable large sets of concentration values in both spatial and temporal domains. LÄS MER
2. Effect of Hyporheic Exchange on Conservative and Reactive Solute Transport in Streams : Model Assessments Based on Tracer Tests
Sammanfattning : Understanding of the processes affecting solute transport in flowing water is important for the possibility to predict the evolution with time of polluted stream systems. This thesis presents tracer experiment methodology and model developments for solute transport in streams, with special focus on retention processes and their effect on solute stream transport.

3. Direct Calculation of Wave-Induced Loads and Fatigue Damage of Container Vessels
Sammanfattning : Container ships and their rules for fatigue design are in several ways differentcompared with other types of commercial ships such as tankers and bulk carriers. Forexample, most modern container ships have a pronounced bow flare and an overhangstern. LÄS MER
4. Solute Transport Across Scales : Time Series Analyses of Water Quality Responses to Quantify Retention and Attenuation Mechanisms in Watersheds
Sammanfattning : The intra-continental movement of waterborne contaminants is governed by the distribution of solute load in the landscape along with the characteristics and distribution of the hydrological pathways that transport the solutes. An understanding of the processes affecting the transport and fate of the contaminants is crucial for assessments of solute concentrations and their environmental effect on downstream recipients.

5. Interactions in aqueous salt solutions : Atomistic modelling versus experiment
Sammanfattning : The research in this thesis investigates how atoms and molecules constituting aqueous salt solutions interact using computational approaches, namely Monte Carlo simulations and molecular dynamics simulations. In the first paper, an atomistic model was developed for aqueous solutions of sodium thiocyanate and potassium thiocyanate (NaSCN and KSCN). LÄS MER
