  2. 11. Ecohydrological water flow analysis of a Swedish landscape in a 100 year perspective

    Author : Lotta Andersson; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : The study basically involves analysis in a 100 year perspective of the hydrological response on precipitation from different landscape elements in south-central Sweden, characterized by the interaction of topography, soil type, land management and canopy cover.For this purpose, a dynamic water partitioning model, based on the soil moisture balance, was developed together with a Geographical Information System (GIS)-supported method for the detection of the spatial distribution of soil wetness as an indicator of the probability to act as discharge or recharge areas respectively.

  4. 12. Groundwater impact assessment and protection

    Author : Åse Eliasson; KTH; []
    Keywords : Physically-based groundwater modelling; contamination; flow and solute transport; glaciofluvial deposits; Nybroåsen; Sweden; and multi-criteria decision-aid;

    Abstract : In the recent decades, therehave been frequent conflicts between groundwater waterresources and environmentally hazardous activities. Newmethodologies for aiding decision-making in groundwater impactassessment and protection areneeded and in which issues ofincreased awareness, better understanding of the groundwaterresources processes, and validation of predictive mathematicalmodels are addressed.

  5. 13. Solute transport in the integrated soil-groundwater system

    Author : Eva Simic; KTH; []
    Keywords : solute transport; groundwater transport; integrated soil.groundwater system;

    Abstract : A Lagrangian stochastic travel time approach has been usedfor investigating dominant process impacts on (non-reactive andreactive) solute transport in the integrated soil-groundwatersystem. A first step has also been taken to extending thisLagrangian stochastic travel time approach to integrate thesoil-groundwater-stream transport through a catchment. READ MORE

  6. 14. Process modeling of liquid composite molding processes

    Author : Da Wu; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Resin cure; Porous media theory; Process modeling; Polymer composites; Liquid composite molding; Fabric composites;

    Abstract : The polymer matrix composites (PMCs) are carving out a niche amid the keen market competition to replace the other material counterparts, e.g., metals. Due to the low weight and the corrosion resistance, the PMCs are wildly utilized from aerospace to automobile industries, both in the sectors of civilian and defense. READ MORE

  7. 15. Impact of Water-Level Variations on Slope Stability

    Author : Jens Johansson; Lars Johansson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Abstract : Waterfront-soil slopes are exposed to water-level fluctuations originating from either natural sources, e.g. extreme weather and tides, or from human activities such as watercourse regulation for irrigation, freshwater provision, hydropower production etc. READ MORE
