  1. 1. Physical microhabitat requirements for Margaritifera margaritifera and the influence of hydro- and morphodynamics on mussel bed stability

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Tove Westberg; [2020]
    Keywords : Stream restoration; Freshwater pearl mussel; Microhabitat requirements; Sediment transport; Mussel translocation;

    Abstract : Margaritifera margaritifera is an endangered freshwater pearl mussel with population declines throughout its Holarctic range. Boulder-bed channels with little input of fine sediment in previously channelized streams are abundant in Sweden. Hence, restoration efforts for M. READ MORE

  2. 2. Temporal and spatial trends of heavy metal leakage from acid sulfate soils : Leakage of Ni, Zn, Cu and Fe to freshwater and marine sediments, North-eastern Sweden

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Bella Blomkvist; [2020]
    Keywords : acid sulfate soils; leaching; Persöfjärden; sulfide oxidation; metal pollution;

    Abstract : Acid Sulfate soils (AS) are recognized for being a source of acidity in freshwaters in America, Europe, Australia, and Asia. Apart from the problematic acid leachate, AS soil serves as a possible source of toxic heavy metals in freshwaters, a problem which has received far less attention than problems related to acid leachate.

  3. 3. Foreland evolution of Blåisen, Norway, over the course of an ablation season

    University essay from Lunds universitet/Geologiska institutionen

    Author : Alexander Hamilton-Foyn; [2020]
    Keywords : Geomorphological Mapping; Structure from Motion; Glacial Landforms; Ice-Marginal Landforms; Landform Preservation; Hardangerjøkulen; Norway; Earth and Environmental Sciences;

    Abstract : This study presents a detailed investigation into the evolution of sedimentary landforms over an ablation season at Blåisen, an outlet of the Hardangerjøkulen Icecap, Norway. The two visits to Blåisen, one each side of the ablation season, allowed the preservation and evolution of the landforms to be studied. READ MORE

  4. 4. Long-term morphological evolution of Cua Lo inlet, Central Vietnam

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Nikita Tegenfeldt; Orio Johansson; [2020]
    Keywords : Inlet morphology; Sand spit; Water exchange; Numerical modelling; Cua Lo river mouth; Sediment transport; Technology and Engineering;

    Abstract : Cua Lo river mouth is a coastal inlet connected to an estuary at the central coast of Vietnam. The area is valuable for maritime trade, fishing industries, and tourism development. Natural disasters during the monsoon period are a problem, causing seasonal flooding. READ MORE

  5. 5. Geomorphic and particle attributes influence on entrainment and sediment transport in semi-alluvial streams

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Joe Sundin; [2020]
    Keywords : Stream geomorphology; Sediment transport; Entrainment; Grain attributes; Bankfull shear stress; Dimensionless critical shear stress; Slope; Boulders; Constrainment;

    Abstract : Streams around the world are shaped by physical processes between water and sediment transport which generates unique geomorphic structures for each stream. This study aimed to evaluated how geomorphic structures and grain attributes would influence entrainment frequency and transport distance of traced clasts. READ MORE
