21. Distributed thermal response tests : New insights on U-pipe and Coaxial heat exchangers in groundwater-filled boreholes
Abstract : U-pipe Borehole Heat Exchangers (BHE) are widely used today in ground source heating and cooling systems in spite of their less than optimal performance. This thesis provides a better understanding on the function of U-pipe BHEs and Investigates alternative methods to reduce the temperature difference between the circulating fluid and the borehole wall, including one thermosyphon and three different types of coaxial BHEs.

22. Altiplanic aquifer exploration by multidisciplinary methods : Addressing the basis of sustainable use of groundwater
Abstract : The sustainable use of groundwater relies on building up three stages: exploration, development and management. The exploration is crucial to understand the capabilities and limitations of aquifer units; e.g. READ MORE

24. Groundwater characterisation and modelling
Abstract : For the last 10 years, the Äspö Hard RockLaboratory (HRL) in Sweden has been the main test site for thedevelopment of suitable methods for the final disposal of spentnuclear fuel. Major achievements have been made in thedevelopment of new groundwater sampling and modellingtechniques. READ MORE

25. Seasonal turnover in groundwater
Abstract : This Licentiate Thesis presents a new approach of understanding leakage in agricultural land. Former studies concentrate on long term measurement of different pollutants in nearby watercourses and streams. The new approach is so far only numerically performed, but will soon be complemented by laboratory tests and field measurements. READ MORE
