  1. 1. Sensitivity analysis of a generic urban flow model : 2D modelling with empirical hyetographs and CDS rain

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Julia Granlund; [2022]
    Nyckelord :Input parameters; initial water content; antecedent moisture content; impervious surfaces; topography; empirical hyetographs; design storms;

    Sammanfattning : Severe flooding events in recent years have underlined the importance of accurate hydrological modelling in urban areas. There are many important parameters relating to both the rainfall distribution and properties of the land on which the rain falls that controls the impacts of the rain event. LÄS MER

  3. 2. Investigating the relationship between circulation patterns and cloudburst character in a changing climate

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Sofia Litsmark; [2020]
    Nyckelord :Circulation patterns; future climate; hyetograph; hyetograph shape; cloudbursts; Cirkulationsmönster; framtida klimat; klimat; skyfall; hyetograf; hyetograf- karaktär; framtida vädermönster;

    Sammanfattning : The consequences of extreme weather in terms of heavy precipitation and flooding are devastating in both rural and urban areas. The cost on society to handle the damages are substantial. It is therefore of high interest to further investigate the mechanisms behind these extreme events. LÄS MER

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

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Michael Henrich; [2019]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

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

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Jimmy Olsson; [2019]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
