  2. 21. Environmental Modelling : Learning from Uncertainty

    Author : John M. Juston; Per-Erik Jansson; Jens Christian Refsgaard; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Models; data; error; uncertainty; hydrology; soil carbon; wetlands; phosphorus;

    Abstract : Environmental models are important tools; however uncertainty is pervasive in the modeling process.   Current research has shown that under­standing and representing these uncertainties is critical when decisions are expected to be made from the modeling results. READ MORE

  4. 22. Modeling flow and sediment transport in water bodies and watersheds

    Author : Muluneh Admass Mekonnen; Bijan Dargahi; Anders Wörman; Hans Bergh; Edward Buchak; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bed load transport model; ECOMSED; Hydrology; Hydrodynamics; Spectral Analysis; SWAT; Water engineering; Vattenteknik;

    Abstract : The research focus is on the various modeling aspects of flow and sediment transport in water bodies and watersheds. The interaction of flow with a mobile bed involves a complex process in which various turbulent scales characterized by coherent structures cause a chaotic sediment motion. READ MORE

  5. 23. Solute Transport Across Scales : Time Series Analyses of Water Quality Responses to Quantify Retention and Attenuation Mechanisms in Watersheds

    Author : Joakim Riml; Anders Wörman; Aaron I. Packman; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Solute transport modeling; Transient storage; Tracer test; Central temporal moments; Spectral analysis; Parameterization;

    Abstract : The intra-continental movement of waterborne contaminants is governed by the distribution of solute load in the landscape along with the characteristics and distribution of the hydrological pathways that transport the solutes. An understanding of the processes affecting the transport and fate of the contaminants is crucial for assessments of solute concentrations and their environmental effect on downstream recipients.

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

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

    Abstract : 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. READ MORE

  7. 25. Managing water according to river basins : Information management, institutional arrangements and strategic policy support - with focus on the EU Water Framework Directive

    Author : Susanna Nilsson; Per-Erik Jansson; Erik Mostert; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; River basin management; EU Water Framework Directive WFD ; River Basin Dis-tricts RBDs ; International cooperation; Indicators; Baltic Sea Region BSR ; Water in nature and society; Vatten i natur och samhälle;

    Abstract : Today, there is a general notion that water resources are best managed according to their river basins. River basin management may be approached from a wide variety of angles. This thesis focuses on information management, institutional arrangements and strategic policy support, with special reference to the EU Water Framework Directive (WFD). READ MORE
