1. 21. Beneficial Use of Stormwater - Opportunities for urban renewal and water conservation

   Författare :Edgar Villarreal-Gonzalez; Avdelningen för Teknisk vattenresurslära; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

3. 22. The Ecological Role of Roadside Stormwater Ponds - Potential to Support Biodiversity

   Författare :Zhenhua Sun; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Macroinvertebrates; Stormwater ponds; DNA metabarcoding; Sediments; High throughput sequencing; Road runoff; Water quality; Aquatic biodiversity;

   Sammanfattning : The increased recognition that roads may impair the aquatic environment and ecosystems has led to a shift from conventional drainage systems toward blue-green solutions such as stormwater ponds. Research on blue-green stormwater solutions has until now mainly focused on water quantity and quality. LÄS MER

4. 23. Assessment of stormwater and snowmelt quality based on water management priorities and the consequent water quality parameters

   Författare :Helen Galfi; Maria Viklander; Jiri Marsalek; Helene Österlund; Jon M. Hathaway; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stormwater quality; indicator bacteria; water quality assessment; VA-teknik; Urban Water Engineering; Centre - Centre for Stormwater Management DRIZZLE ; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ;

   Sammanfattning : Stormwater and snowmelt pollution contributes to degradation of quality of the receiving waters. For assessing such impacts, it is effective to focus on specific causes of degradation, as done in this study of the quality of stormwater and snowmelt discharges into the receiving waters serving for supply of raw drinking water and water-based recreation.

5. 24. Urban Surfaces as Sources of Stormwater Pollution : An Evaluation of Substances Released from Building Envelopes

   Författare :Alexandra Müller; Maria Viklander; Helene Österlund; Jiri Marsalek; Per-Arne Malmqvist; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering; Centre - Centre for Stormwater Management DRIZZLE ; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ;

   Sammanfattning : Stormwater is an important transport pathway for pollutants from the urban environment into receiving water bodies, and, thus, it contributes to the deterioration of urban surface waters. The aim of this Licentiate thesis was to advance the understanding of the contributions of urban stormwater pollutants from building surface materials, and evaluate the implications for stormwater quality.

7. 25. Future trends in urban stormwater quality : effects of changes in climate, catchment characteristics and processes and socio-economic factors

   Författare :Matthias Borris; Lian Lundy; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

   Sammanfattning : Climate change and progressing urbanization cause numerous environmental concerns, including the impacts on urban drainage. Such impacts were addressed during the last two decades with focus on hydraulic overloading of drainage systems and the means of overload remediation by stormwater management. LÄS MER
