2. 1. Water and Heat Transport in Road Structures : Development of Mechanistic Models

   Author : Klas Hansson; Lars-Christer Lundin; Kurt Roth; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydrology; Water flow; Heat flow; Unsaturated flow; Freeze-thaw; Numerical models; Uncertainty analysis; Sensitivity analysis; Roads; Overland flow; Flow patterns; TDR; Water content reflectometer; Calibration; Fractures; Hydrologi; Hydrology; Hydrologi;

   Abstract : The coupled transport of water and heat, involving freezing and thawing, in the road structure and its immediate environment is important to consider for optimal design and maintenance of roads and when assessing solute transport, of e.g. de-icing salt, from roads. READ MORE

4. 2. Water Quality in Swedish Lakes and Watercourses : Modeling the Intra-Annual Variability

   Author : Julia Hytteborn; Kevin H. Bishop; Andreas C. Bryhn; Johan Temnerud; Bergström Ann-Kristin; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Total organic carbon; cyanobacteria; seasonality; water quality modeling; climate change; surface water; Earth Science with specialization in Environmental Analysis; Geovetenskap med inriktning mot miljöanalys;

   Abstract : Water quality is of great importance for ecosystems and society. This thesis characterized and modeled the variation in several key constituents of Swedish surface waters, with particular consideration given to intra-annual variability and sensitivity to climate change. READ MORE

5. 3. Subsurface dams in water resource management : methods for assessment and location

   Author : Imran Ali Jamali; Bo Olofsson; Stephen Foster; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Subsurface dams; Groundwater; GIS; Regolith thickness; Groundwater; Byggvetenskap; Civil and Architectural Engineering;

   Abstract : Natural groundwater storage can be improved by constructing a subsurface barrier that is a subsurface dam, in order to capture the subsurface flows and raise the groundwater levels (GWLs) in the sediment layers. Subsurface dams are preferable to surface dams because of lower evaporation, higher functionality, lower cost of construction, lessened risk for contamination and the possibility of utilizing land over the dam.

6. 4. Spatially Distributed Hydrological Modelling : Wetness Derived from Digital Elevation Models to Estimate Peatland Carbon

   Author : Abdulghani Hasan; Institutionen för naturgeografi och ekosystemvetenskap; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; modelling hydrology; Digital elevation models; LiDAR data; topographic wetness index; GIS; permafrost; Stordalen; peatland;

   Abstract : To study the hydrology of peatlands and explore wetness distribution is difficultmainly due to the complexity of the surface of peatlands, and also due to the presence of permafrost underlain peatlands in the arctic regions. I have chosen the area called Stordalen mire in the arctic region in northern Sweden for my study. READ MORE

7. 5. Molecular Copper and Ruthenium Water Oxidation Electrocatalysts for Light-Driven Water Splitting

   Author : Ludovico Riccardi; Sascha Ott; Rene Janssen; Jarl Van der Vlugt; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Water oxidation; Molecular catalyst; Electrocatalyst; Water splitting; Electrolyzer; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

   Abstract : In recent years, there has been a growing awareness of the need to transition to renewable energy to mitigate the effects of climate change and reduce greenhouse gas emissions. Governments, businesses, and individuals are investing in renewable energy infrastructure and technologies to create a more sustainable energy future. READ MORE
