  1. 1. The hydrodynamic impacts of Estuarine Oyster reefs, and the application of drone technology to this study

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Oskar Evert Johansson; [2021]
    Keywords : Geography; Geographical Information Systems; GIS; Physical Geography; Oyster Reef; Drone; UAV; Hydrodynamics; Earth and Environmental Sciences;

    Abstract : The impacts of climate change are being seen within the estuarine environment through erosion and shoreline retreat, associated with sea-level rise and changes in storm activity. Restoration oyster reefs have been identified as a working-with-nature strategy to protect and restore these shoreline environments, stabilising sediment, and reducing erosion. READ MORE

  3. 2. Soil erosion by water : Estimating soil loss and sediment yield in the southern half of Sweden by using the Revised Universal Soil Loss (RUSLE) model

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Ella Myr; [2021]
    Keywords : Soil erosion; water erosion; soil loss; RUSLE; rainfall erosivity; soil erodibility;

    Abstract : Soil erosion has been recognized as an increasing threat to the environment and humans worldwide as anthropogenic activities have accelerated the soil degradation rate. In Sweden, it is estimated that 15% of the arable land is affected by soil erosion, and studies have shown that fields in the south of Sweden lose a substantial amount of soil under certain weather conditions.

  4. 3. Methods for measuring mercury in gas ebullition from fiber banks : A literature study

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Diana Jonsson; [2021]
    Keywords : Fiber bank; fiber rich-sediment; mercury; contaminants; gas ebullition; pulp-fiber; wood industry; paper industry; environmental toxicity; wood waste;

    Abstract : Mercury contamination is an environmental issue with high priority due to its high toxicity. In addition to the atmospheric deposition, several lakes and rivers in Sweden are contaminated as a result from wood and pulp-fiber industries which stretches back 200 years. READ MORE

  5. 4. Stratigraphy and dating of a lake sediment record from Lyngsjön, eastern Scania : human impact and aeolian sand deposition during the last millennium

    University essay from Lunds universitet/Geologiska institutionen

    Author : Marijana Stevic; [2019]
    Keywords : aeolian activity; human impact; geochemistry; lake sediments; pollen; Earth and Environmental Sciences;

    Abstract : A small lake in north-eastern Scania, southern Sweden, Lake Lyngsjön, reveals a long history of aeolian sand drift based on a 3 meter long sediment sequence covering the last approximately 1400 years. Human impact, primarily through intensified land use and decreased forest cover, has periodically led to increased aeolian sand drift both locally and regionally. READ MORE

  6. 5. Evaluation of Impacts from River Engineering Measures at Nanjing Reach of Yangtze River : An Application of Hydrodynamic Modelling and Sediment Transportation Simulations

    University essay from Uppsala universitet/Elektricitetslära

    Author : Daniel Håkansson; Marcus Palmquist; [2014]
    Keywords : Nanjing Reach of Yangtze River; Hydrodynamic model; Sediment transportation; River engineering; Baguazhou Island;

    Abstract : The demand of electric power has rapidly increased in China along with the financial development. High pollution rates have pushed the development towards more renewable energy generating alternatives. In recent years larger investments of hydropower- generated electricity have been to satisfy the increased demand. READ MORE
