1. Risk Estimation of Groundwater Drawdown in Subsidence Sensitive Areas
Sammanfattning : Groundwater drawdown induced ground subsidence is a severe problem in many regions around the world. Leakage of groundwater into a sub-surface construction, resulting in drawdown and subsequent subsidence, can lead to immense damage costs on buildings and installations in urban areas. LÄS MER
2. Value of Information Analysis in Rock Engineering Investigations
Sammanfattning : A challenge in rock engineering is to strike a balance between a reasonable level of investigation and uncertainty in the geological conditions. Value of Information Analysis (VOIA) provides support for decisions about investigation strategies. LÄS MER
3. Geosystem services to support decisions on subsurface use
Sammanfattning : Awareness of the subsurface is in general low and is not a daily concern for decision-makers. This often results in that decisions on access to subsurface resources instead are guided by a ‘first come, first served principle’. LÄS MER
4. The Impact of Fracture Geometry on the Hydromechanical Behaviour of Crystalline Rock
Sammanfattning : Effective construction of tunnels in fractured crystalline rock requires a unified approach for handling rock mechanics and hydrogeological issues. Traditionally, rock mechanics and hydrogeology not only use different nomenclature, they also measure parameters such as e.g. aperture differently. LÄS MER
5. Arsenic in Alluvial Aquifers in the Meghna Basin, Southeastern Bangladesh : Hydrogeological and Geochemical Characterisation
Sammanfattning : Elevated levels of arsenic (As) in Bangladesh groundwater has emerged as a massive calamity exposing a large population to the risk of As toxicity from drinking water sources and agricultural products. Holocene alluvial aquifers in the delta- and flood-plains of the Ganges-Brahmaputra- Meghna (GBM) river systems are severely affected by high levels of As in groundwater. LÄS MER
