  1. 1. Surface and Subsurface Flow Connection and Dominating Runoff Mechanism in Hillslope of Tarfala, Northern Sweden.

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Namika Maharjan; [2023]
    Nyckelord :Advanced Terrestrial Simulator ATS ; hillslope connectivity; tracer test; hydrological modeling; parameter analysis; sub artic regions; hillslope hydrology;

    Sammanfattning : The Sub artic regions are becoming increasingly important due to the effects of climate change. In northern Sweden, thawing of permafrost has led to significant increases in annual minimum flows in several catchments. LÄS MER

  3. 2. 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.

  4. 3. A coupling method using CFD, radiative models and a surface model to simulate the micro-climate

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Joseph Vernier; [2023]
    Nyckelord :Computational Fluid Dynamics; Fluid Mechanics; Numerics; Micro-climate modeling; Radiation; Crop modeling; Photovoltaic panels;

    Sammanfattning : The increasing demand for energy, depletion of fossil fuels, rising global warming, and greenhouse gas emissions have stimulated the need for widespread development and adoption of renewable energy sources (RES) worldwide. Among these sources, solar energy has emerged as a major contender to meet the growing demand. LÄS MER

  5. 4. Impacts of peatland drainage on soil properties : a study of drainage effects on boreal peatlands in northern Sweden

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

    Författare :Frederika Klaus; [2022]
    Nyckelord :Boreal peatlands; Bulk density; Carbon; Greenhouse gas; Isotopes; Nitrogen; Organic matter; Peatlands; Peatland drainage; Peatland restoration;

    Sammanfattning : Peatlands cover approximately 3% of the terrestrial surface on Earth and perform several important ecosystem functions, such as carbon storage and water retention. During the late 19th and early 20th centuries, approximately 2 million hectares of peatlands in Sweden were drained to manage the land for forestry and agriculture. LÄS MER

  7. 5. Analysis of the water quality dynamics of Lake Vomb; Interactions between water quality profile and cyanobacterial bloom in a eutrophic lake in Sweden

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Wiebke Coenen; [2022]
    Nyckelord :Vombsj¨on; Lake profile; Cyanobacteria; Drinking water; Random Forest; Technology and Engineering;

    Sammanfattning : Lake Vomb, located in Sk˚ane, Sweden, provides water for groundwater infiltration, used for the drinking water supply of several municipalities, including Malm¨o. The lake is in a bad ecological condition with intense algae blooms during summer. Cyanobacteria dominate mentioned blooms in 2021 posing the threat of releasing cyanotoxins. LÄS MER
