  1. 1. Pluvial urban flooding in a densified Sweden : do sustainable flood management and densification fit together?

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Helena Arro; [2023]
    Keywords : urban flooding; pluvial urban flooding; sustainable urban flood management; technological fix; densification;

    Abstract : Pluvial urban flooding occurs in many parts of the world, including Sweden, often with severe consequences. Climate change and increased urbanization exacerbate the risk of urban flooding, and traditional urban drainage systems are unable to keep up. READ MORE

  3. 2. 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

  4. 3. 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.

  5. 4. 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

  6. 5. 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
