2. 1. 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

4. 2. 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

5. 3. Evolution of a silicic magma reservoir in the upper crust : Reyðarártindur pluton, Southeast Iceland

   Author : Emma Rhodes; Steffi Burchardt; Abigail Barker; Charles F. Parker; Alexander Cruden; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; magma; magma emplacement; magma reservoir; floor subsidence; piecemeal subsidence; granite; pluton; cap-rock; magma mingling; magma plumbing systems; volcanic and igneous plumbing systems; eruption; Geovetenskap med inriktning mot mineralogi; petrologi och tektonik; Earth Science with specialization in Mineral Chemistry; Petrology and Tectonics;

   Abstract : Field observations of extinct and exposed magma reservoirs shed light on processes operating in the roots of presently active volcanoes. The Reyðarártindur pluton, Southeast Iceland is an example of a fossil shallow magma reservoir that fed eruptions. READ MORE

6. 4. Numerical analyses of the hangingwall at the Kiirunavaara mine

   Author : Tomas Villegas; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

   Abstract : The mining method used in the Kiirunavaara Mine induces failure in the hangingwall which caves and subsides by the effect of stress relaxation and gravity. Since the orebody is dipping towards the city of Kiruna, surface disturbances are approaching the town as mining proceeds to a greater depth. READ MORE

7. 5. Structural and sedimentological reconstruction of the inverted Vargfors basin : a base for 4D-modelling

   Author : Tobias Bauer; Peter Sorjonen-Ward; Luleå tekniska universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Malmgeologi; Ore Geology;

   Abstract : The Palaeoproterozoic Skellefte mining district in northern Sweden covers an area of 120 by 30 km and is one of the most important mining districts in Europe, producing mainly Zn, Cu, Pb, As and Au from volcanogenic massive sulfide (VMS) and orogenic gold deposits.Detailed mapping of structures and stratigraphy within the sedimentary Vargfors Group combined with a structural analysis revealed a syn-extensional fault pattern of NW-SE-trending normal faults and associated NE-SW-trending transfer faults, creating the segmented sedimentary Vargfors basin.
