  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. From precipitation to stream

    University dissertation from Institutionen för anläggning och miljö

    Author : Andres Peralta Tapia; Sveriges lantbruksuniversitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Understanding the journey water makes from precipitation entering a catchment, traveling through soils, and the time it takes before it exits as stream water are questions of great relevance for both scientists and environmental managers. Natural stable isotopes such as δ¹⁸O and δ²H have been extensively used over the last decades to trace water through diverse catchments across the world. READ MORE

  4. 4. 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.

  5. 5. Conceptualizing catchment processes affecting stream chemistry

    University dissertation from Uppsala : Uppsala universitet

    Author : Tejshree Tiwari; Sveriges lantbruksuniversitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Maintaining good surface water quality is recognized as one of the greatest challenges for future generations. In northern-latitudes, it is predicted that aquatic ecosystems may experience a large climatic change. READ MORE
