1. Modelling the Water Table in a Bog
Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Over the past five years, an ongoing study at INES, Lund University, have examined the encroachment of trees and vegetation into a bog ecosystem in northern Scania, Sweden. While several factors have been identified as contributing to this ecological transformation, including, nutrient availability, and climate, the hydrological aspect remains a key area of investigation.

2. Grundvattenbildning i Alnarpsströmmen. Numerisk modellering av grundvattenbildning och akvifersförhållanden.
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)Sammanfattning : I Sverige är grundvatten är en av de huvudsakliga källorna för dricksvatten. Grundvattenmagasin kommer att påverkas av klimatförändringar genom förändrad effektiv nederbörd och således grundvattenbildning. LÄS MER
3. Idealised remediation scenario in two small-scale intersecting fractures
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : Analysis of mass transport in rock fractures has become increasingly important in underground storage of radioactive materials and remediation of polluted groundwater in fractured rock aquifers. Permeability of rock mass is regulated by present rock fractures, where flow is mainly through the fracture networks. LÄS MER
4. Performance Evaluation of a High Temperature Borehole Thermal Energy Storage Under Influence of Groundwater Flow
Master-uppsats, KTH/EnergiteknikSammanfattning : Recent years have seen a growing interest in large-scale high-temperature borehole thermal energy storage (HT-BTES) as a means to store industrial waste heat and solar energy between the seasons. A profound understanding and characterization of the thermal and hydraulic processes involved in such systems is required for the optimal design as well as for environmental assessments of the storage.

5. Design and Optimisation of an Aquifer Storage and Recovery System - Options for long term storage under natural hydraulic gradients
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Teknisk geologiSammanfattning : Aquifer storage and recovery (ASR) is a concept where water is stored in an aquifer during times when it is available, thus creating artificial groundwater, which can later be recovered by pumping when it is needed (Pyne, 1995). One ASR cycle consists of a injection, a standby and a recovery phase. LÄS MER
