  1. 1. Hydrological Transport in Shallow Catchments: : tracer discharge, travel time and water age

    Författare :Sofie Safeyeh Soltani; Vladimir Cvetkovic; Bijan Dargahi; Jan Olof Selroos; Andrea Rinaldo; KTH; []
    Nyckelord :Hydrological transport; travel time; water age; tracer discharge; Lagrangian pathway approach; pathway lengths; numerical modeling; Land and Water Resources Engineering; Mark- och vattenteknik;

    Sammanfattning : This focuses on hydrological transport in shallow catchments with topography-driven flow paths. The thesis gives new insight to kinematic pathway models for estimation of tracer discharge at the catchment outlet. LÄS MER

  3. 2. The Lagrangian Stochastic Advective-Reactive Approach to Modeling Solute Transport in Hydrological Systems

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

    Sammanfattning : 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. LÄS MER

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

    Författare :Eva Simic; KTH; []
    Nyckelord :solute transport; groundwater transport; integrated soil.groundwater system;

    Sammanfattning : 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. LÄS MER

  7. 5. REACTIVE TRANSPORT MODELLING OF DISSOLVED CO2 IN POROUS MEDIA : Injection into and leakage from geological reservoirs

    Författare :Nawaz Ahmad; Anders Wörman; Auli Niemi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CO2 geological storage and safety; leakage of brine saturated with dissolved CO2; reactive transport; fracture; advection; dispersion and diffusion; sorption; carbonate minerals kinetic reactions; calcite; dolomite; siderite; porosity; permeability; heat transport; Land and Water Resources Engineering; Mark- och vattenteknik;

    Sammanfattning : The geological sequestration of carbon dioxide (CO2) is one of the options of controlling the greenhouse gas emissions. However, leakage of CO2 from the storage reservoir is a risk associated with geological sequestration. Over longer times, large-scale groundwater motion may cause leakage of dissolved CO2 (CO2aq).
