1. 1. Monitoring transport and fate of de-icing salt in the roadside environment : Modelling and field measurements

   Författare :Annika Lundmark; Per-Erik Jansson; Bo Olofsson; Ann-Catrine Norrström; Helen K. French; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chloride; De-icing salt; Groundwater; Modelling; Monitoring; Road; Roadside; Soil water; Water in nature and society; Vatten i natur och samhälle;

   Sammanfattning : Roads and traffic are a major non-point source of pollutants and may have severe impacts on surface water, groundwater, soil and vegetation. In cold climates, de-icing salt is one such pollutant that may cause increased chloride concentrations and induce other effects on the environment. LÄS MER

3. 2. Groundwater Recharge in Crystalline Bedrock : Processes, Estimation, and Modelling

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

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

4. 3. Groundwater characterisation and modelling

   Författare :Marcus Laaksoharju; KTH; []
   Nyckelord :;

   Sammanfattning : For the last 10 years, the Äspö Hard RockLaboratory (HRL) in Sweden has been the main test site for thedevelopment of suitable methods for the final disposal of spentnuclear fuel. Major achievements have been made in thedevelopment of new groundwater sampling and modellingtechniques. LÄS MER

5. 4. Heterogeneity-Induced Channelling, Flow-Wetted Surface, and Modelling of Transport in Fractured Rock

   Författare :Martin Larsson; Auli Niemi; Chin-Fu Tsang; VLADIMIR CVETKOVIC; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; channelling; flow-wetted surface; fractured rock; solute transport; groundwater modelling; groundwater; Hydrology; Hydrologi;

   Sammanfattning : Heterogeneities in fractured rock are found at all scales; from the scale of individual fractures, to the scale of fracture networks, and to the largest regional scales. These heterogeneities cause challenges for modelling and parameter estimation of flow and solute transport. LÄS MER

7. 5. Modelling of Groundwater Conditions in Silts and Fine Sands. A Study of Induced Groundwater Changes Based on Laboratory and Full-Scale Field Tests

   Författare :Marius Tremblay; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fine sand; laboratory tests; numerical simulation; silt; soil mechanics; groundwater; pore pressure; field tests; soil matric suction; partially saturated soil; groundwater conditions;

   Sammanfattning : Every day, geotechnical engineers have to deal with groundwater problems. In order to find suitable solutions to these problems, modelling of the groundwater conditions and their variations in time has to be performed. A study of the groundwater conditions in silts and fine sands was made including laboratory and full-scale field tests. LÄS MER
