2. 1. Road disasters? Modeling and assessment of Swedish roads within crucial climate conditions

   Author : Alireza Nickman; Bo Olofsson; Per-Erik Jansson; Nils-Otto Kitterød; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Road; Flood; Moisture; Temperature; Groundwater; GIS; Uncertainity; Sweden; Mark- och vattenteknik; Land and Water Resources Engineering;

   Abstract : An efficient maintenance of roads to ensure high accessibility and durability of the transport capacity requires an understanding of how the hydrological response depends on both the road and the landscape characteristics. New methods and data were used to identify and explain interaction between roads and surrounding environment and their influence on hydrologic responses both in watershed scale and road-section scale.

4. 2. Multimethod characterization of a chlorinated solvents contaminated site and geoelectrical monitoring of in-situ bioremediation

   Author : Aristeidis Nivorlis; Teknisk geologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geoelectrical monitoring; induced polarization 1P ; contamination remediation geophysics; Time-lapse inversion; autonomous geophysical monitoring;

   Abstract : Soil contamination is a widespread problem and actions need to be taken in order toprevent damage to the groundwater and the life around the contaminated sites. InSweden more than 80.000 sites are potentially contaminated, therefore there is ademand for accurate and efficient methods for site characterization and soilremediation. READ MORE

5. 3. Integrated analyses and interpretations of regional scale magnetotelluric and potential field data from the Precambrian crust of northern Sweden

   Author : Roshanak Vadoodi; Thorkild Maack Rasmussen; Maxim Smirnov; Björn H. Heincke; Luleå tekniska universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Exploration Geophysics; Prospekteringsgeofysik;

   Abstract : The Norrbotten region in northern Sweden, as a part of the Fennoscandian (Baltic) Shield, is one of the most active mining areas in Europe. It is acknowledged that geological structures such as faults, shear zones, and associated fracture systems play a key role in providing a physical pathway connecting metal sources and the sites of mineral precipitation.

6. 4. Analysis of Excavation Damage, Rock Mass Characterisation and Rock Support Design using Drilling Monitoring

   Author : Jeroen van Eldert; Håkan Schunnesson; Daniel Johansson; David Saiang; Thomas Dalmalm; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Blast damage; Excavation Damage Zone; EDZ; Measurement While Drilling; MWD; Rock support; Rock mass characterisation; Tunnelling; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

   Abstract : Prior to an underground excavation a site investigation is carried out. This includes reviewing and analysing existing data, field data collected through outcrop mapping, drill core logging and geophysical investigations. READ MORE

7. 5. Geometrical controls on spectral induced polarization in time and frequency domain

   Author : Sara Johansson; Teknisk geologi; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spectral induced polarization; Microstructure; Electrical properties; Tomography; Multiscale;

   Abstract : What can we learn by transmitting electrical currents through electrodes in the ground? Geophysical methods can help us to locate the bedrock, valuable mineral ores, remains of ancient buildings and many other secrets hiding below the surface. However, it is not only the universal interest for the unknown that drives the geophysical research forward. READ MORE
