  1. 16. Road runoff quality in cold climates

    Författare :Camilla Westerlund; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Sammanfattning : The main objective of the doctoral thesis was to investigate the complex processes and influencing factors affecting snowmelt-induced runoff and snowmelt quality in a cold climate under wintry conditions compared to non- winter conditions in areas with a warmer climate. In order to improve the understanding and knowledge of road-runoff quantity, quality and pollutant transport, snowmelt and rainfall runoff were studied and characterized in the laboratory and in the field, respectively.

  2. 17. Building a coherent hydro-climatic modelling framework for the data limited Kilombero Valley of Tanzania

    Författare :Alexander Koutsouris; Steve W. Lyon; Jan Seibert; Mekonnen Gebremichael; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hydrology; Precipitation; Recession analysis; End - member mixing analysis; EMMA; GLUE; HBV; down scaling; Quantile mapping; CFSR; CMORPH; CRU; GPCC; ERA - i; MERRA; TRMM; UDEL; Satellite; Reanalysis; Kilombero; Tanzania; Eastern Africa; Africa; Physical Geography; naturgeografi;

    Sammanfattning : This thesis explores key aspects for synthesizing data across spatiotemporal scales relevant for water resources management in an Eastern Africa context. Specifically, the potential of large scale global precipitation datasets (GPDs) in data limited regions to overcome spatial and temporal data gaps is considered. LÄS MER

  3. 18. Climate and geographical influence on the performance of infiltration-based facilities for managing runoff – Temporal and spatial variability

    Författare :Ivan Mantilla; Maria Viklander; Tone Merete Muthanna; Kelsey Flanagan; Vegard Nielsen; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Green infrastructure; hydrological performance; infiltration capacity; climatic pattern; saturated hydraulic conductivity; VA-teknik; Urban Water Engineering;

    Sammanfattning : Climate change is expected to lead to more intense and severe rainfall events in the future, significantly increasing the risk of urban flooding. This change, characterized by spatial and temporal shifts in precipitation patterns, presents a challenge to the capacity of existing urban drainage systems, which may lead to higher runoff volumes than they were initially designed to handle.

  4. 19. Green roof vegetation and storm water runoff quantity - Effects of plant traits, diversity and life strategies

    Författare :Joel Lönnqvist; Godecke-Tobias Blecken; Maria Viklander; Ishi Buffam; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ; Centre - Centre for Stormwater Management DRIZZLE ;

    Sammanfattning : Green roofs have gained recognition and popularity globally for their potential to help mitigate the negative impacts of urbanization such as habitat loss and disruption of the water cycle caused by increased impervious surfaces. However, there is still a need to enhance our understanding of green roof vegetation dynamics and how they affect plant water use and hydrological function under varying environmental conditions.

  5. 20. Urban stormwater systems in future climates : assessment and management of hydraulic overloading

    Författare :Karolina Berggren; Adrian Saul; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Sammanfattning : Increasing global temperatures and tendencies of more frequent extreme weather events have been observed over the recent decades, and the continuation of this trend is predicted by future climate models. Such climatic changes impact on many human activities and hence the interest in, and focus on, climate change has increased rapidly in recent years. LÄS MER
