  1. 1. Peakflow response of stream networks implications of physical descriptions of streams and temporal change

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Anna Åkesson; KTH.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Streamflow routing; peakflow predictions; parameterization; hydrological response; stage-dependency; flooded cross-sections; stream networks; backwater effects; temporal change; land use change; Byggvetenskap; Civil and Architectural Engineering;

    Abstract : Through distributed stream network routing, it has quantitatively been shown that the relationship between flow travel time and discharge varies strongly nonlinearly with stream stage and with catchment-specific properties.Physically derived distributions of water travel times through a stream network were successfully used to parameterise the streamflow response function of a compartmental hydrological model.

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

    University dissertation from Institutionen för anläggning och miljö

    Author : Archana Gupta; KTH.; [2000]
    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

  3. 3. Water chemistry and runoff in forest streams at Kloten

    University dissertation from Uppsala : Uppsala universitet

    Author : Harald Grip; Uppsala universitet.; [1982]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Element clustering; evapotranspiration; impact; Hydrology; Hydrologi;

    Abstract : Natural variability of stream water composition and discharge was studied in the Kloten area, Central Sweden, by means of statistical methods and simulation technique. The effects of Urea (155 kgN ha-1) and ammonium nitrate (AN, 160 kgN ha-1) fertilization and clear-cutting were studied by comparing treated and reference streams before and after management.

  4. 4. Water quality modeling based on landscape analysis: importance of riparian hydrology

    University dissertation from Stockholm : Department of Physical Geography and Quaternary Geology, Stockholm University

    Author : Thomas Grabs; Stockholms universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Water quality model; terrain analysis; geographical information system GIS; riparian zone; total organic carbon TOC; boreal catchments; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences Hydrology; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap Hydrologi; Physical Geography; geografi med naturgeografisk inriktning;

    Abstract : Several studies in high-latitude catchments have demonstrated the importance of near-stream riparian zones as hydrogeochemical hotspots with a substantial influence on stream chemistry. An adequate representation of the spatial variability of riparian-zone processes and characteristics is the key for modeling spatio-temporal variations of stream-water quality. READ MORE

  5. 5. Atmospheric and oceanic circulation from a thermodynamic perspective

    University dissertation from Stockholm : Department of Meteorology, Stockholm University

    Author : Aitor Aldama Campino; Kristofer Döös; Peter Lundberg; George Nurser; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Atmospheric circulation; Ocean circulation; Stream functions; Atmospheric Sciences and Oceanography; atmosfärvetenskap och oceanografi;

    Abstract : The climate system is continuously transporting and exchanging heat, freshwater, carbon and other tracers in different spatio-temporal scales. Therefore, analysing the system from a thermodynamic or biogeochemical framework is highly convenient. READ MORE
