  1. 1. 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

  3. 2. Estimation of flood risk and cost-effective mitigations : A case study in Tierp

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Anton Blomqvist; Stephanie The; [2023]
    Keywords : Flood risk assessment; EAD; CADSS; MIKE21;

    Abstract : Climate change is predicted to alter the rainfall patterns in the future, and extreme rain events with large rainfall volumes will become more frequent and intense which increases the flood risk. A clear trend can be seen, where more and more people decide to relocate from rural to urban areas. READ MORE

  4. 3. How variations of the duration and time to peak of the Chicago Design Storm affect the hydraulic response, as well as the areas contributing to peak runoff, of a synthetic urban catchment area

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Oskar Ahlstedt; [2022]
    Keywords : Avrinningsområde; översvämningsmodellering; peak-bidragande område; hydrograf; hyetograf; MIKE 21; regnintensitet; CDS-regn; Chicago Design Storm;

    Abstract : With an expanding urbanization in the world, and thus the expansion of impermeable surfaces, the risk of pluvial floods is an increasing factor that needs to be considered. This, in combination with increasing rain intensities and frequency of rain events indicates a problem both today and for the future. READ MORE

  5. 4. Flood modelling in urban areas : A comparative study of MIKE 21 and SCALGO Live

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Evelina Andersson; [2021]
    Keywords : SCALGO Live; MIKE 21; Stormwater Model; Flood Model; Cloudburst; Inundation; Comparative;

    Abstract : Pluvial flooding originating from extreme rainfall is problematic and an increasing issue in Sweden. Higher requirements on adapting cities in urban areas to these challenges have been placed on both municipalities and the county administration. Thus, an increased need for water modelling, both in existing and planned areas have emerged. READ MORE

  6. 5. Opportunities for increased nutrient recovery at centralised wastewater treatment plants through urine separation

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Hanna Gustavsson; [2021]
    Keywords : Nutrient recovery; urine separation; magnesium ammonium phospahte; MAP; ammonium sulphate; AMS; and DHI s WEST;

    Abstract : Municipal wastewater contains a significant amount of nutrients such as phosphorus (P) and nitrogen (N). Therefore have the interest of recovering these nutrients at wastewater treatment plants (WWTP) increased. Nutrient recovery would generate revenue for the WWTP, as it is possible to sell the products as fertiliser. READ MORE
