1. 1. Storm Water Management with BlueGreen Infrastructure in Urban Planning : A case-study in Krokom, Sweden

   University essay from Mittuniversitetet/Institutionen för naturvetenskap, design och hållbar utveckling (2023-)

   Author : Lena Suleiko Allansson; [2023]
   Keywords : Sustainable drainage system SuDS ; nature-based solutions; ecosystem services; urban water management; climate change adaption;

   Abstract : As changing climate and growing urban populations present new challenges for managing both the quantity and the quality of storm waterin cities, nature-based solutions such as blue-green infrastructure arebecoming widely considered as an alternative to grey infrastructure. The benefits, above providing storm water management at a lower cost, are increased ecosystem services. READ MORE

   University essay from KTH/Urbana och regionala studier

   Author : Linn Johansson; [2023]
   Keywords : Stormwater; social sustainability; stormwater management; rainwater; biodiversity; recreation;

   Abstract : This project is established on the following questions:  How can Stockholm adapt to increasing extreme rainfall events through combined stormwater drainage strategies?How can social sustainability be implemented in stormwater treatment?How can stormwater and social design educate the public about the importance of clean water bodies?  Global and national trends show that annual precipitation is increasing, and extreme weather events are becoming more common. Urban landscapes are more susceptible to cloudburst flooding due to impervious surfaces. READ MORE

4. 3. Modelling the risk of rainfall events leading to momentary pollution levels exceeding maximum allowed concentrations - A Swedish case study of urban runoff in the Fyris river

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Tove Gannholm Johansson; [2022]
   Keywords : urban runoff; flow; rain event; pollution concentration; EQS; MAC-EQS; dagvatten; flöde; regntillfälle; föroreningskoncentration; MKN; MAC-MKN;

   Abstract : The purpose of this study was (1) to study the proportion (X) of the flow in a watercourse that consists of urban runoff during a rain event and (2) to evaluate the risk that a few chosen pollutants, transported by urban runoff, exceed the maximum allowed concentration in the watercourse according to the environmental quality standards (MAC-EQS). The Fyris river in Uppsala, Sweden, was selected as a case study. READ MORE
