  1. 6. Investigating the impact of the Millennium Drought on catchment water balance : A study of four catchments in Victoria, Australia

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Linn Sundström; [2018]
    Nyckelord :Catchment water balance; catchment behavior; groundwater storage; specific yield; Millennium Drought.;

    Sammanfattning : Southeast Australia have between 1997-2009 experienced a severe drought, referred to as the Millennium Drought. During these years the region experienced a 11.4% decline in mean annual rainfall, an unprecedented decrease in runoff and a decline in soil moisture and groundwater storage. LÄS MER

  3. 7. Modeling copper pollution from road Runoff in a peri-urban catchment in Portugal by using MIKE SHE, and MIKE 11 coupled with ECO Lab

    Master-uppsats, KTH/Mark- och vattenteknik

    Författare :Ricardo Valencia Gudiño; [2017]
    Nyckelord :Copper modelling; hydrology; water quality; MIKE 11 - ECO Lab;

    Sammanfattning : Economic development in an area attracts more people to live in it. This increment drives the necessity to improve available infrastructure, like roads for instance, to satisfy a higher demand. LÄS MER

  4. 8. A multi-scale based method for estimating coniferous forest aboveground biomass using low density airborne LiDAR data

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

    Författare :Jialong Duanmu; [2016]
    Nyckelord :individual tree identification; multi-scale; aboveground biomass AGB ; LiDAR; remote sensing; GEM; Earth and Environmental Sciences;

    Sammanfattning : Forest biomass acts as an important indicator of carbon resources in terrestrial system. Estimation of forest biomass enables a straightforward measurement of carbon storage and provides initial values for process-based carbon cycle models to simulate carbon dynamics. LÄS MER

  5. 9. Local and landscape effects on the diversity of plant communities in Swedish beaver ponds

    Master-uppsats, SLU/Dept. of Aquatic Sciences and Assessment

    Författare :Joel Lönnqvist; [2014]
    Nyckelord :beaver pond; Castor fiber; aquatic plants; hydrophytes; helophytes; macrophytes; landscape; nitrogen; plant dispersal; catchment;

    Sammanfattning : The European beaver Castor fiber is considered an ecosystem engineer and a key species because of its dam building behavior. Little is known about the factors affecting plant diversity in beaver impounded streams. This study aimed to investigate if local and landscape variables affect plant diversity of beaver ponds.

  7. 10. Clear-cut Effects on Snow Accumulation and Evapotranspiration in a Boreal Catchment in Northern Sweden

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Mikaela Rudling; [2013]
    Nyckelord :: Clear-cut; HBV; boreal forest; runoff; evapotranspiration; snow accumulation; avverkning; HBV; avrinning; evapotranspiration; snöackumulering;

    Sammanfattning : The aim of this thesis was to investigate the processes behind an unexpected runoff behaviour after a clear-cut in a boreal forest in northern Sweden (Balsjö). The risks of increased flooding, erosion, nutrient leakage and changes in the local ecosystems are some reasons why it is important to fully understand the effect of clear-cuts on the water balance.
