  2. 21. Water and Heat Transport in Road Structures : Development of Mechanistic Models

    Author : Klas Hansson; Lars-Christer Lundin; Kurt Roth; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydrology; Water flow; Heat flow; Unsaturated flow; Freeze-thaw; Numerical models; Uncertainty analysis; Sensitivity analysis; Roads; Overland flow; Flow patterns; TDR; Water content reflectometer; Calibration; Fractures; Hydrologi; Hydrology; Hydrologi;

    Abstract : The coupled transport of water and heat, involving freezing and thawing, in the road structure and its immediate environment is important to consider for optimal design and maintenance of roads and when assessing solute transport, of e.g. de-icing salt, from roads. READ MORE

  5. 23. Changes in the Freshwater System : Distinguishing Climate and Landscape Drivers

    Author : Fernando Jaramillo; Georgia Destouni; Zbigniew W. Kundzewicz; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Budyko; evapotranspiration; freshwater; hydrology; hydroclimatic change; landscape change; land use; observation data; runoff; separation; water partitioning; water storage change; water use; worldwide; Physical Geography; naturgeografi;

    Abstract : Freshwater is a vital resource that circulates between the atmosphere, the land and the sea. Understanding and quantifying changes to the partitioning of precipitation into evapotranspiration, runoff and water storage change in the landscape are required for assessing changes to freshwater availability.

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

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

    Abstract : 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. READ MORE

  7. 25. Physical process effects on catchment-scale pollutant transport-attenuation, coastal loading and abatement efficiency

    Author : Georg Lindgren; Georgia Destouni; Roko Andricevic; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Efficient pollutant load abatement; groundwater-surface water interactions; biogeochemical cycles; nitrogen; Lagrangian stochastic travel time approach; GIS; Hydrology; Hydrologi;

    Abstract : Pollutants follow various subsurface and surface water pathways from sources within a catchment to its outlet and may cause detrimental effects on downstream water quality and ecosystems. Along their different transport pathways through a catchment, pollutants may be attenuated subject to different physical and biogeochemical processes. READ MORE
