  1. 1. Hydrological Seasonal Forecasting

    Författare :Kean Foster; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; hydrological seasonal forecasting; seasonal forecast; spring flood; multi-model ensembles; teleconnection patterns; modelling chain;

    Sammanfattning : In Sweden, almost half of the electricity produced comes from hydropower. However, the amount of water in the reservoir catchments is not evenly distributed throughout the year. During the colder months, precipitation usually falls as snow and accumulates into a snowpack. LÄS MER

  3. 2. 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

  4. 3. Hydrological effects of water harvesting techniques

    Författare :Slah Nasri; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; soil mechanics; Väg- och vattenbyggnadsteknik; offshore technology; hydraulic engineering; hydrological effects; Civil engineering; rainwater harvesting; erosion;

    Sammanfattning : The thesis investigates hydrological effects of large-scale water harvesting techniques on local water balances as well as sediment erosion. The techniques of tabias, soil contour ridges and small hill reservoirs are investigated. Pertinent processes are observed and simulated using various hydrological models.. LÄS MER

  5. 4. Dam safety in a hydrological perspective-Case study of the historical water system of Sala Silver Mine

    Författare :Tina Fridolf; KTH; []
    Nyckelord :dam safety; design flood; flood mitigation; hydrological; risk assessment;

    Sammanfattning : The old water system in Sala, formerly belonging to thesilver mine, is analysed with regard to dam safety focusing onthe hydrological aspects. The hydrological safety of the riskclass I dams in the area, built in the 16th century, is notconsidered adequate according to the Swedish guidelines fordesign flood determination. LÄS MER

  7. 5. Hydrological Modeling for Climate Change Impact Assessment : Transferring Large-Scale Information from Global Climate Models to the Catchment Scale

    Författare :Claudia Teutschbein; Jan Seibert; Chris Kilsby; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bias Correction; Climate Change; Climate Models; Ensembles; GCM; HBV; Hydrological Modeling; Precipitation; RCM; Split Sample Test; Streamflow; Sweden; Temperature; Uncertainty; Physical Geography; naturgeografi;

    Sammanfattning : A changing climate can severely perturb regional hydrology and thereby affect human societies and life in general. To assess and simulate such potential hydrological climate change impacts, hydrological models require reliable meteorological variables for current and future climate conditions. LÄS MER
