  1. 1. 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

  3. 2. Tungmetaller i dagvattendammar : en jämförelse mellan beräknade och uppmätta årsmedelhalter i inkommande dagvatten

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Mathias Andersson; [2019]
    Keywords : Germans formel; StormTac; flödesproportionell vattenprovtagning; tungmetaller; dagvatten;

    Abstract : Dagvatten som rinner längs hårdgjorda ytor i stadsmiljöer kan föra med sig tungmetaller och andra föroreningar från ytorna. Vanligtvis transporteras det förorenade dagvattnet via led- ningsnäten till en recipient där det riskerar att förorena sjöar och vattendrag. READ MORE
