  1. 1. Reningseffekten av fosfor och kväve i regnbäddar

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Elnaz Habibi; [2021]
    Keywords : regnbädd; biofilter; näringsämnen;

    Abstract : Flera hårdgjorda ytor och mindre vegetation i våra städer har orsakat att den naturliga infiltrationen minskar. Hårdgjorda ytorna gör att det blir en snabb avrinning som den traditionella dagvattensystem inte kan klara av. Detta ökar risken för översvämningar samt ger negativa effekter till miljön. READ MORE
