1. 6. Evaluating the Bluespot model with the August 2021 flood in Gävle, Sweden

   University essay from Stockholms universitet/Institutionen för naturgeografi

   Author : Oskar Björklund; [2023]
   Keywords : Bluespot model; Urban Pluvial Flood Model; Fill Spill Merge Model; Gävle Flood 2021.;

   Abstract : Floods are one of the most common types of natural disasters. They annually affect vast amounts of people and cause severe economic losses. While fluvial, coastal, and flash floods are well studied, pluvial floods (rain related) have received modest attention from researchers and decision-makers in comparison. READ MORE

3. 7. The influence of infiltration and rain intensity on an urban pluvial flood model : A case study of a catchment in Malmö municipality

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Emma van Heek; Ellen Persson; [2023]
   Keywords : Urban pluvial flooding; hydraulic model; type event; infiltration; runoff coefficient; Urban pluvial översvämning; hydraulisk modell; typ-regn; infiltration; avrinningskoefficient;

   Abstract : Urban pluvial floods have become more and more common in Europe. These floods have resulted in high costs for society, increasing the interest in conducting hydraulic flood models. This in order to prepare and minimise the consequences of these flood events. READ MORE

4. 8. 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

5. 9. 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

6. 10. The influence of spatial variations in rain intensity for cloudburst modelling : a case study of the Gävle cloudburst

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Fanny Jeppsson Stahl; [2022]
   Keywords : Flood modelling; pluvial flooding; spatial variations in rain intensity; design storms; MIKE 21 Flow Model FM; 2D hydraulic modelling; Skyfallsmodellering; pluviala översvämningar; spatiala variationer i regnintensitet; typregn; MIKE 21 Flow Model FM;

   Abstract : With an intensification of heavy rain events in a changing climate and a rapid urbanization the risk for pluvial flooding is increasing in our societies. Pluvial flooding, which is formed when the rainfall rate exceeds the infiltration or drainage rate, can occur rapidly and cause great damages, large economic losses and possibly risk human lives.
