  1. 1. Riparian plant biodiversity and community composition of ditches and straightened streams : identifying key environmental drivers in a boreal forest setting

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

    Author : Rasmus Staaf; [2024]
    Keywords : artificial waterways; riparian zone; novel ecosystems; ; forestry; ditch network maintenance; species richness; hill-diversity; drainage ditches; coarse woody debris; ditch cleaning; ecology;

    Abstract : Modified ecosystems are typically seen as degraded and having no ecological value. In many cases, the modification of the ecosystem was done more than 100 years ago and may have had time to recover and become a refugia for species that were once more common in the landscape.

  2. 2. Kvillebäcken : analys och gestaltningsförslag - me[d]andra strukturer och processer

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Louise Stigsson Rigné; Emil Vernersson; [2024]
    Keywords : Urbanekologi; landskapsarkitektur; hydrologi; vattendrag; naturbaserade lösningar; blågrön infrastruktur;

    Abstract : I byggandet av hållbara städer är utveckling av blågrön infrastruktur högaktuell, och inom detta faller stort fokus på utveckling av urbana vattendrags ekologi, vattenkvalitet, och förmåga att omhänderta konsekvenser av klimatförändringar. Få vattendrag uppnår miljökvalitetsnormerna, och platsspecifika utmaningar finns i varje vattendrag. READ MORE

  3. 3. Coupling between iron and humic substances in a land-sea transitional zone in the northern Baltic Sea

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

    Author : Anna Osterman; [2023]
    Keywords : Iron; Humic substances; Dissolved organic carbon; Baltic Sea; Rivers;

    Abstract : In marine ecosystems around the world, iron (Fe) is a well-studied and important trace element which has been found to stimulate phytoplankton and cyanobacteria growth, as well as limit nitrogen fixation and being essential for Legionella pneumophila which is known as the main cause of Legionnaires’ disease. Fe also contributes to the brownification of freshwater and has recently been documented to increase in concentration in rivers in Sweden. READ MORE

  4. 4. Impact of wetland restoration on river discharge - A case study of Bråån, Skåne, Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Ardis Luda; [2023]
    Keywords : wetlands; wetland restoration; HYPE model; river discharge; Sweden; land use change; flooding; hydrological modeling; Earth and Environmental Sciences;

    Abstract : Land use change is a factor not often considered when modeling river discharge in regard to future flood risk. The restoration of wetlands is an ongoing land use change which affects water storage capacity in the soils of a catchment and could lead to lower flows in rivers. READ MORE

  5. 5. Lifetime CostEffectiveness of Constructed Wetland and Rain Garden Facilities in Relation to Expected  Treatment Performance

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Abdullah Noorhussin Ali; [2023]
    Keywords : Stormwater; Total cost; StormTac; Cost-effectiveness;

    Abstract : The purpose of this thesis is to investigate the cost effectiveness of two different stormwater control measure (SCM) facilities, namely a constructed wetland in Boden and a rain garden in Gothenburg (both Sweden), in relation to treatment efficiency and contributing catchment area. The study approach involved collection of data, construction, and maintenance activities with their respective costs, for the two stormwater control measures from commercial and literature data.
