  1. 1. Modelling the Water Table in a Bog

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Tobias Bowley; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Over the past five years, an ongoing study at INES, Lund University, have examined the encroachment of trees and vegetation into a bog ecosystem in northern Scania, Sweden. While several factors have been identified as contributing to this ecological transformation, including, nutrient availability, and climate, the hydrological aspect remains a key area of investigation.

  3. 2. Analysis of Rainfall-runoff processes at different scales in two mountainous, Arctic catchments in northern Sweden

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :June Johansson; [2023]
    Nyckelord :Arctic hydrology; Catchment response parameters; Water height recession analysis; Permafrost presence; Glacier presence;

    Sammanfattning : The hydrological regime in Arctic catchments is being altered as an effect of climate change. To be able to project future changes in Arctic hydrology and hydrogeology, the mechanisms and drivers affecting runoff generation needs to be understood. LÄS MER

  4. 3. SWAT Runoff Modeling and Salinity Estimation in the Odra River Catchment

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Tassilo Thebe; [2023]
    Nyckelord :;

    Sammanfattning : In 2022, a significant fish die-off happened in the Odra River due to a bloomof the toxic gold algae species Prymnesium parvum, which occurs in saline andwarm waters. This event is seen as a major ecological disaster in recent Europeanriver incident history. LÄS MER

  5. 4. What has happened on Swedish mires? The effects of drainage on vegetation changes over recent decades

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Anna Ljungqvist; [2022]
    Nyckelord :peatlands; mires; bogs; fens; sweden; vegetation; plant ecology; time trend; data; nfi; nils; climate change; global warming; mosses; sphagnum; afforestation; trees; wetland; presence; coverage; drainage; ditch;

    Sammanfattning : As they are not only the home of many threatened species, but also one of the main actors in the global carbon cycle, peatlands are highly valuable ecosystems. Human disturbance, in particular drainage for forestry and agriculture, has substantially changed the state of the world’s peatlands and will continue to do so. LÄS MER

  7. 5. Modelling the Human-Flood Interactions : Effects of different societal risk perceptions on flood losses

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

    Författare :Zhixian Hu; [2022]
    Nyckelord :Socio-hydrological modelling; risk perception; flood risk management; Sociohydrologisk modellering; riskperception; hantering av översvämningsrisk;

    Sammanfattning : Can one society’s flood risk perception and management strategy impact the neighbouring society? This study applies a socio-hydrological model to four ideal types of society living along the same river. These societies have various rationalities and risk perceptions: risk-controlling, risk-monitoring, risk- neglecting and risk-downplaying. LÄS MER
