  1. 16. 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

  3. 17. 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

  4. 18. Metal mobility and transport from an oil-shale mine, Lake Nõmmejärv, Estonia

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Åsa Ekelund; [2020]
    Keywords : Mine waste; Heavy metals; Oil shale; Lake sediments; Lake Nõmmejärv; Human impact; Kurtna kame field; Estonia.;

    Abstract : Mining activities have a large impact on the environment, for example by the release of heavy metals from acid mine drainage and erosion of mine waste. North-eastern Estonia has the largest commercially exploited oil-shale deposit in the world. READ MORE

  5. 19. 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

  6. 20. Modelling Water Exchange in the Flommen Lagoon, South Sweden

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Shuwei Wang; [2019]
    Keywords : Water exchange; Coastal lagoon; The Flommen Lagoon; The Falsterbo Peninsula; Longshore sediment transport; Numerical modelling; Inlet morphology; Technology and Engineering;

    Abstract : The Flommen Lagoon in southern Sweden is surrounded by several natural reserves and is an important bird migration site on the edge of the continent. The protection of this area including water quality in the lagoon and flooding problems in the adjacent area has always been a concern. READ MORE
