2. 1. Traffic-related pollutants in urban snow : Concentrations, size fractionation, and release with snowmelt

   Author : Arya Vijayan; Maria Viklander; Helene Österlund; Göran Blomqvist; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Urban snow; Traffic pollution; Suspended solids; Metals; PAHs; Tire and Road wear Particles T RWPs ; Microplastics MPs ; Size fractionation; VA-teknik; Urban Water Engineering; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ; Centre - Centre for Stormwater Management DRIZZLE ;

   Abstract : In urban areas with seasonal snow, traffic-related pollutants such as solid particles, metals, chloride, organic pollutants, and microplastics (MPs) can be temporarily stored in snowbanks along roads and streets. When the snow melts, it releases the accumulated pollutants and the resulting snowmelt with diverse pollutants may partly infiltrate into the ground, or enter storm sewers and eventually be discharged into, and impact on, the receiving waters.

4. 2. Urban wastewater systems: From disposal to reuse. A study of different systems with focus on water and nutrients flows

   Author : Justyna Czemiel Berndtsson; Avdelningen för Teknisk vattenresurslära; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Storm Water; Urban; Wastewater; Civil engineering; offshore technology; hydraulic engineering; Väg- och vattenbyggnadsteknik; soil mechanics; pollution control; Environmental technology; Miljöteknik; kontroll av utsläpp; Nutrients;

   Abstract : Urban wastewater systems are currently exposed to a major rethink dictated by new demands on resource management. It is postulated that next to providing efficient sanitation (preventing spread of pathogenic microorganisms) these systems should support resource reuse. READ MORE

5. 3. Grassed swales for urban storm drainage

   Author : Magnus Bäckström; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

   Abstract : This thesis investigates the environmental, economic and functional aspects of using grassed swales for the conveyance and treatment of stormwater. A grassed swale is a shallow, grass-lined channel. READ MORE

6. 4. Beneficial Use of Stormwater - Opportunities for urban renewal and water conservation

   Author : Edgar Villarreal-Gonzalez; Avdelningen för Teknisk vattenresurslära; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; soil mechanics; Väg- och vattenbyggnadsteknik; offshore technology; hydraulic engineering; Civil engineering; water conservation; rainwater collection; Best Management Practices; Urban stormwater; green-roofs; open drainage systems;

   Abstract : This thesis investigates the beneficial use of stormwater in Swedish urban environments. The focus has been on open stormwater systems for source control, as well as rainwater collection systems. To analyse the implementation of open stormwater systems, two case studies are presented: Augustenborg in Malmö and Bäckaslöv wetland in Växjö. READ MORE

7. 5. Green Urban Drainage Infrastructure : Hydrology and Modelling of Grass Swales

   Author : Hendrik Rujner; Maria Viklander; Günther Leonhardt; Jiri Marsalek; Barraud Sylvie; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ; Centre - Centre for Stormwater Management DRIZZLE ;

   Abstract : The management of urban runoff has evolved along with the advancement of understanding of runoff environmental impacts. Besides the impacts on water quality in the receiving waters, the impacts on the urban hydrologic regime include reduced infiltration by the sealing of pervious land, reduced evapotranspiration by removal of vegetation, and the resulting increase of stormwater runoff peaks and volumes causing flooding, and ultimately degradation of receiving waters.
