  1. 1. Initial nutrient retention capacity in a constructed wetland : Evaluating the effectiveness of a newly constructed wetland to reduce eutrophication symptoms in a Baltic Sea bay in northern Sweden

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

    Author : Elin Eriksson; [2021]
    Keywords : retention; constructed wetland; total phosphorus; total nitrogen; nutrient dynamics; northern latitudes; nutrient mitigation measure;

    Abstract : Since the turn of the last century, a substantial increase in nutrient load to the Baltic Sea is apparent. Adding the ongoing environmental change with raising temperatures and increased precipitation, this will continue to have a prominent environmental impact on our coastal ecosystems, especially in northern latitudes.

  3. 2. 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

  4. 3. Evaluation of potential marine current turbine sites in North American waters

    University essay from Uppsala universitet/Elektricitetslära

    Author : Tim Andersson; Muhammad Arsal Akram; Carl-Henrik Carlnäs; Tiffany Salisbury; [2020]
    Keywords : vertical axis; marine current turbines; alaska; florida;

    Abstract : Suitable locations for marine current power generation were scouted. The specific turbines considered in this project are vertical axis turbines and require an water velocity of 0.8 m/s to start and has a system efficiency of 20%. READ MORE

  5. 4. Modelling of Water Exchange in Flommen Lagoon System in Skanör-Falsterbo, Sweden

    Abstract : The Flommen Lagoon system is located in Skanör-Falsterbo, Sweden. It hosts a diverse and sensitive ecosystem. There have been concerns about the water quality in this lagoon due to impaired water exchange. READ MORE

  6. 5. Records of environmental change and sedimentation processes over the last century in a Baltic coastal inlet

    University essay from Lunds universitet/Geologiska institutionen

    Author : Hanna Nilsson; [2019]
    Keywords : Baltic Sea; eutrophication; coastal areas; archipelago; laminated sediments; nutrient inputs; carbon and nitrogen content; biogenic silica; sedimentation; environmental impact; marine geology; Earth and Environmental Sciences;

    Abstract : The marine ecosystem in the Baltic Sea is affected by multiple stress factors, e.g. eutrophication and deoxygenation, overfishing and anthropogenic pollution. Here we evaluate the short-term trends of dissolved oxygen in bottom waters and changes in the primary productivity within a coastal inlet in the Baltic Sea. READ MORE
