  1. 1. Intensiv nederbörd och pluviala översvämningar i Umeå

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Elsa Lindgren; [2022]
    Nyckelord :Extreme precipitation; pluvial floods; climate change; solid surfaces; Umeå; extrem nederbörd; pluviala översvämningar; klimatförändringar; hårdgjorda ytor; Umeå;

    Sammanfattning : During intensive rainfall, the ground is at risk of flooding if the water has no opportunity to infiltrate into the ground or drain. Cities are most heavily affected by such pluvial floods due to their predominantly solid surfaces. LÄS MER

  2. 2. Developing a Rainfall-Runoff Routing Model using  Spatially Distributed Travel Times : Modelling a Cloudburst Event in an Urban Catchment

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

    Författare :Sara Ekeroth; [2022]
    Nyckelord :Excess rainfall; Runoff routing; Cloud burst; Pluvials; GIS; ArcPy; Effektiv nederbörd; Avrinningsmodell; Skyfall; Pluviala översvämningar; Geodata; ArcPy;

    Sammanfattning : The future holds challenges for urban areas when it comes to handling pluvial floodings, occurring when the rainfall intensity exceeds both the man-made and natural infiltration and drainage capacity. To gain understanding of the effects and needed measures, tools for modelling the urban response to events such as cloudbursts are needed. LÄS MER

  3. 3. Implementation of Citizens’ Observations in Urban Pluvial Flood Modelling

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

    Författare :Fredrik Schück; [2021]
    Nyckelord :Calibration; Crowdsourcing; Citizen science; CDS-rainfall; 2D flood model; Spatial variability;

    Sammanfattning : Damages caused by urban pluvial floods are believed to increase due to climate change and urbanization as more citizens are impacted in densely populated cities and extreme rainfalls occur more frequently with higher intensities. To prepare cities for these calamities, urban pluvial flood models are created to provide knowledge about how an extreme rainfall event could inundate the studied city. LÄS MER

  4. 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
