  1. 1. Sediment transport in small streams is related to riparian buffer width : a comparison between wide and narrow riparian buffers

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Rasmus Staaf; [2022]
    Keywords : Riparian Zone; Protective Zone; Headwater Stream; Forestry; Clear – cut Harvest; Organic Sediment; Inorganic Sediment; Near Stream Logging;

    Abstract : This study aims to provide information about how different widths of riparian buffers affect the quantity and quality of sediments transported in a small stream after a clear – cut harvest. Small streams have critical influences on downstream rivers and excessive transported sediments can have large negative effects on the aquatic system. READ MORE

  3. 2. 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

  4. 3. Optimizing the design of two-stage ditches to improve nutrient and sediment retention

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Sofia Englund; [2020]
    Keywords : eutrophication; water quality; mitigation measure; two-stage ditch; retention time; water retention; nutrients; sediments; vegetation; terrace; HEC-RAS; Manning’s coefficient; water level; climate change; övergödning; vattenkvalitet; begränsande åtgärd; tvåstegsdike; retentionstid; vattenretention; näringsämnen; sediment; vegetation; terrass; HEC-RAS; Manning’s koefficient; vattennivå; klimatförändring;

    Abstract : Negative effects on water quality are created by eutrophication of the world’s water resources. Mitigation measures have been implemented, but poor improvements in water quality have been observed. Two-stage ditches have the possibility to increase nutrient and sediment retention to reduce eutrophication in receiving water bodies. READ MORE

  5. 4. Tungmetaller i dagvattendammar : en jämförelse mellan beräknade och uppmätta årsmedelhalter i inkommande dagvatten

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Mathias Andersson; [2019]
    Keywords : Germans formel; StormTac; flödesproportionell vattenprovtagning; tungmetaller; dagvatten;

    Abstract : Dagvatten som rinner längs hårdgjorda ytor i stadsmiljöer kan föra med sig tungmetaller och andra föroreningar från ytorna. Vanligtvis transporteras det förorenade dagvattnet via led- ningsnäten till en recipient där det riskerar att förorena sjöar och vattendrag. READ MORE
