  1. 1. Hur kan infiltration i åkermark beskrivas vid skyfallskartering?

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Anna Hilgers; Linnea Ahl; [2020]
    Nyckelord :skyfallmodellering; skyfallskartering; infiltration; jordbruksmark; åkermark; modellering; Technology and Engineering;

    Sammanfattning : I denna rapport undersöktes hur infiltration i åkermark kan beskrivas i en skyfallskartering. Utifrån en fördjupad litteraturstudie av åkermarkens egenskaper och särart valdes en uppsättning parametrar för att beskriva dess infiltration. LÄS MER

  3. 2. Dissolved organic matter (DOM) quality in agricultural streams and its impact on carbon dioxide concentrations in stream water

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Karin Broqvist; [2018]
    Nyckelord :DOM quality; dissolved organic matter; DOC; PARAFAC; fluorescence; streams; agriculture; fluorescence index; freshness index; humification index; carbon dioxide; DOM kvalitet; löst organiskt material; DOC; PARAFAC; fluorescens; bäckar; jordbruk; fluorescence index; freshness index; humification index; koldioxid;

    Sammanfattning : Inland waters have lately been recognized to be an important component in the carbon cycle, having a significant role in carbon sequestration and carbon dioxide (CO2) emissions. Attention has also been drawn to the impact of the quality (i.e. composition and source) of dissolved organic matter (DOM) on CO2 production. LÄS MER

  4. 3. Know the flow - spatial and temporal variation of DOC exports and the importance of monitoring site specific discharge

    Master-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Johannes Larson; [2018]
    Nyckelord :dissolved organic carbon; DOC; export; boreal; specific discharge; spatiotemporal variation; löst organiskt kol; DOC; export; boreal; specifik avrinning; spatiotemporal variabilitet;

    Sammanfattning : The export of dissolved organic carbon (DOC) is an important component in both water quality and carbon cycling within boreal catchments. DOC exports are mainly controlled by discharge. LÄS MER

  5. 4. Climate change impact on water balance and export of dissolved organic carbon : a sub-catchment modelling approach

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Stina Sandgren; [2017]
    Nyckelord :HYPE; hydrological modelling; DOC; climate change; water balance; specific discharge; hydrology; climate scenarios; carbon cycle; mire catchment; forest catchment; Earth and Environmental Sciences;

    Sammanfattning : Climate change will alter the hydrological cycle in the 21st century with implications for the water balance and water quality. As characteristics of the landscape may vary significantly between nearby locations, hydrological models need to be able to delineate responses attributed to specific landscape characteristics, to estimate their responses to altered climatic drivers.

  7. 5. Variable Specific Discharge and Its Influence on Mass Export of Carbon, Sulphur, Calcium and Magnesium in a Boreal Forest Catchment

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Isabell Gärtner; [2016]
    Nyckelord :Hydrochemistry; hydrology; specific discharge; boreal catchment; Hydrokemi; hydrologi; avrinning; avrinningsområde i barrskog;

    Sammanfattning : Considerable research efforts are made in order to understand the global carbon cycle and how it will affect future climate change and vice versa. To be able to calculate the export of carbon from a certain area, discharge is one of the most important variables together with stream concentrations. LÄS MER
