1. 1. 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

3. 2. The influence of temporal rainfall distribution and storm movement on flood depth in urban pluvial cloud burst modeling

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Michael Henrich; [2019]
   Keywords : Pluvial flooding; cloud burst; flood modeling; MIKE 21; temporal distribution; storm movement; areal reduction factors; ARFs; hyetograph; design storm; CDS; Pluviala översvämningar; skyfall; översvämningsmodellering; MIKE 21; regnmönstrets tidsfördelning; molnrörelse; areal reduktion av nederbörd; ARFs; hyetograph; typregn; CDS;

   Abstract : Pluvial floods are the most difficult and to date least investigated phenomena in urban hydrology. While efforts are being made to increase the knowledge base concerning this type of flooding, a large part of the difficulty lies in the nature of the precipitation. READ MORE

4. 3. The influence of storm movement and temporal variability of rainfall on urban pluvial flooding : 1D-2D modelling with empirical hyetographs and CDS-rain

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

   Author : Jimmy Olsson; [2019]
   Keywords : pluvial flooding; flood modelling; 1D-2D modelling; MIKE FLOOD; MIKE 21; MIKE URBAN; storm movement; temporal variability; hyetograph; design storm; Chicago Design Storm; CDS-rain; pluviala översvämningar; översvämningsmodellering; 1D-2D modellering; MIKE FLOOD; MIKE 21; MIKE URBAN; molnrörelse; hyetograf; typregn; Chicago Design Storm; CDS-regn;

   Abstract : Pluvial floods are formed directly from surface runoff after extreme rain events. Urban areas are prone to suffer from these floods due to large portions of hardened surfaces and limited capacity in the stormwater infrastructure. Previous research has shown that catchment response is influenced by the spatio-temporal behaviour of the rainstorm. READ MORE

5. 4. High resolution ensemble flood forecasting

   University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Author : Cajsa-Lisa Ivarsson; [2019]
   Keywords : High-resolution; rainfall-runoff modelling; flood forecasting; HYPE; pluvial floods; Technology and Engineering;

   Abstract : The number and impacts of pluvial floods are likely to increase with the growth of our cities and as extreme weather is anticipated to intensify with climate change. Im- proved preparedness is needed which may be attained owing to recent development of high-resolution hydro-meteorological observations and forecasts as well as geographical data. READ MORE

6. 5. Planning support for reducing risks related to flooding : A case study of flood response in Kista residential area and Igelbäcken stream, Sweden

   University essay from KTH/Mark- och vattenteknik

   Author : Kajsa Lundgren; [2017]
   Keywords : Planning support; blue green solutions; hydrodynamic modelling; MIKE FLOOD; climate change adaption; land use change; Planeringsstöd; blå-gröna lösningar; hydrodynamiskmodellering; MIKE FLOOD; klimatanpassning; markanvändning;

   Abstract : Flooding has been identified as the most widespread and most frequently occurring natural disaster by the United Nation. Sweden is no exception when it comes to being affected by flooding, and several major flood events have been seen in recent years. READ MORE
