2. 1. Towards prediction in ungauged aquifers – methods for comparative regional analysis

   Author : Ezra Haaf; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Groundwater; Prediction in ungagued aquifers; Comparative hydrogeology; Similarity; Groundwater hydrographs; Groundwater dynamics; Time series clustering; Groundwater climate interaction; Classification; Regression; Groundwater storage; Groundwater resources management;

   Abstract : Hydrogeological investigations and in particular groundwater resource assessments are strongly reliant on understanding the factors controlling groundwater level dynamics. However, historical records of measured groundwater levels are often scarce and unevenly distributed in space and time. READ MORE

4. 2. Strategic groundwater protection

   Author : Cecilia Scharp; KTH; []
   Keywords : ;

   Abstract : Groundwater is an undervalued natural resource that isexperiencing a large number of threats to both its quantity andquality. Different types of land-use activities releasepotentially harmful substances that may be transported down tothe groundwater and have a negative impact on its quality. READ MORE

5. 3. Risk Estimation of Groundwater Drawdown in Subsidence Sensitive Areas

   Author : Jonas Sundell; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; uncertainty quantification; urban hydrogeology; pore pressure reduction; subsidence; geostatistics; groundwater leakage; soft soil; groundwater drawdown; spatial variability; settlement; probabilistic; risk assessment;

   Abstract : 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. READ MORE

6. 4. Risk Assessment of Groundwater Drawdown in Subsidence Sensitive Areas

   Author : Jonas Sundell; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; inverse modelling; cost-benefit analysis; probabilistic; groundwater drawdown; urban hydrogeology; economic valuation; groundwater leakage; subsidence; value of information analysis.; spatial variability; uncertainty quantification; risk assessment;

   Abstract : Groundwater leakage into sub-surface constructions can result in drawdown, subsidence in compressible materials, and costly damage to buildings and installations. When planning for sub-surface constructions where there is a risk for land subsidence due to groundwater drawdown, the need for safety measures must be carefully evaluated and managed. READ MORE

7. 5. Groundwater Recharge in Crystalline Bedrock : Processes, Estimation, and Modelling

   Author : Niclas Bockgård; Sven Halldin; Allan Rodhe; Auli Niemi; Lars O. Ericsson; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydrology; groundwater recharge; bedrock; crystalline rocks; tracers; CFC; surface loading; loading efficiency; barometric effect; heterogeneity; stochastic modelling; Hydrologi; Hydrology; Hydrologi;

   Abstract : Kunskap om grundvattenbildningen är nödvändig för att man ska kunna förutsäga konsekvenserna av grundvattenuttag och underjordsbyggande. Grundvattenbildningen i berggrunden är dock svår att uppskatta. READ MORE
