  2. 16. 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

  4. 17. Stochastic analysis of fluid flow and tracer pathways in crystalline fracture networks

    Author : Andrew Frampton; Vladimir Cvetkovic; Allen Shapiro; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Groundwater; Fractured media; Transport; Retention; Macrodispersion; Lagrangian formulation; Stochastic modelling; Earth sciences; Geovetenskap; Hydrology; Hydrologi; Environmental engineering; Miljöteknik;

    Abstract : Understanding groundwater flow systems and how these control transport is an essential part in assessing the suitability of subsurface environments as hosts for storage of toxic waste. Therefore it is important to be able to integrate knowledge obtained from field characterisation of the subsurface with methods which can be used to evaluate and predict possible impact on surrounding environments.

  5. 18. Modelling Hydrological and Hydrodynamic Processes in Lake Tana Basin, Ethiopia

    Author : Shimelis Gebriye Setegn; Bijan Dargahi; Nicola Fohrer; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lake Tana; Climate Change; SWAT; Hydrological Modeling; Hydrodynamic; GEMSS; MCE; Streamflow; Sediment yield; Hydrology; Hydrologi; Water engineering; Vattenteknik;

    Abstract : Lake Tana Basin is of significant importance to Ethiopia concerning water resources aspects and the ecological balance of the area. The growing high demands in utilizing the high potentials of water resource of the Lake to its maximal limit, pictures a disturbing future for the Lake. READ MORE

  6. 19. The Integrated Distributed Hydrological Model, ECOFLOW- a Tool for Catchment Management

    Author : Nikolay Sokrut; Roger Thunvik; Tuomo Karvonen; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydrogeology; Multiple-scale hydrological modelling; Bayesian algorithm; Parameter estimation; Groundwater management; Statistical analysis; Hydrogeologi; Hydrology; Hydrologi;

    Abstract : In order to find effective measures that meet the requirements for proper groundwater quality and quantity management, there is a need to develop a Decision Support System (DSS) and a suitable modelling tool. Central components of a DSS for groundwater management are thought to be models for surface- and groundwater flow and solute transport. READ MORE

  7. 20. The Lagrangian Stochastic Advective-Reactive Approach to Modeling Solute Transport in Hydrological Systems

    Author : Archana Gupta; KTH; []
    Keywords : solute transport; groundwater transport; unsaturated zone; stream hydrology; stream networks; stochastic processes; mass transfer kinetics; preferential flow; temporal moments; catchment hydrology; Lagrangian transport model;

    Abstract : The Lagrangian stochastic advective-reactive modelingapproach has been used for analyzing transport of bothnonreactive and reactive solutes in different hydrologicalsystems (structured soil, groundwater, mining waste rockdeposits and surface waters including single stream and networkof streams) and at different spatio-temporal scales (rangingfrom laboratory column-scale to catchment-scale). Further, afirst step has been taken to extending the Lagrangianstochastic advective-reactive modeling methodology to integratethe soil-groundwater-stream transport through a catchment. READ MORE
