1. 1. Näringsförluster från sju jordbruksområden nära Mälaren

   University essay from SLU/Dept. of Soil and Environment

   Author : Sally Karlsson Bondesson; [2024]
   Keywords : avrinningsområde; belastning; fosfor; kväve; S-HYPE; retention; typområden på jordbruksmark; vattenflöde; VISS; våtmark;

   Abstract : Ett av Sveriges miljömål är ”ingen övergödning” vilket innebär att gödande ämnen inte ska ha negativ inverkan på människor, biologisk mångfald eller mark-och vattenanvändning (Naturvårds-verket 2023). Näringsämnena fosfor och kväve och förlusten av dessa från framför allt jordbruksmark är en av orsakerna till övergödning i sjöar, hav och vattendrag. READ MORE

3. 2. 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.

4. 3. Modelling the Impact of Climate and Socio-Economic Changes on Nutrient Dynamics in the Catchment of Lake Vomb

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Yanhe Zhou; [2023]
   Keywords : Climate change; hydrological modelling; nutrient; RCP; socioeconomic development; SSP; SWAT; water quality modelling;

   Abstract : Climate change and socio-economic development are greatly affecting the quality of freshwater, especially the excessive accumulation of nutrients (N and P), which eventually leads to the occurrence of eutrophication. Lake Vomb is one of the main sources of drinking water in southern Sweden and the nutrient load from the catchment makes it a eutrophic lake with recurring algal blooms. READ MORE

5. 4. Bluegreengrey (BGG) solution for future climate and flood-resilient urban drainage network by enhancing the natural hydrological cycle

   University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Author : Adnan Asif Rifat; [2023]
   Keywords : Bluegreengrey; Sustainable stormwater; Basement flooding; Urban flooding; Pipe Network; BGG; Climate change; Hydrology; Mike .; Technology and Engineering;

   Abstract : A loop of urbanization, increasing impervious surface in urban areas, increasing temperature, rainfall, surface runoff and flooding, and lack of new spaces have been adding challenges to urban drainage systems for decades. The climate change impacts are exposing the existing vulnerable conventional urban drainage systems to more challenges in the future. READ MORE

6. 5. Nutrient Retention in Constructed Wetlands

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Johanna Kero; [2022]
   Keywords : Constructed wetlands; nutrient retention; phosphorus; nitrogen; catchment area factors; Anlagda våtmarker; näringsretention; fosfor; kväve; avrinningsområdesfaktorer;

   Abstract : Eutrophication, a surplus of nutrients, is a problem in aquatic environments and one of the Swedish Environmental Goals is that there should be no eutrophication caused by human activities. Constructed wetlands (CW:s) is a measure that could be implemented to decrease the transport of nutrients to water bodies through retention. READ MORE
