Vi formar framtidens arkitekter och samhällsbyggare. Genom utbildning och forskning inom ingenjörs- och samhällsvetenskap, arkitektur och humaniora, utvecklar vi kunskap och nya lösningar till nytta för ett hållbart samhälle.

Vi arbetar med nya lösningar för det du ser, och för det du inte ser men använder, upplever och är beroende av, i ditt hem och i den byggda miljön du vistas i. Alltifrån undermarkskonstruktioner, avfall, vatten, avlopp och installationer i inomhusmiljön, till transportsystem, infrastruktur och planering och utformning av byggnader och hela städer. Vår ambition är att inspirera och motivera att ta itu med och lösa globala, samhälleliga utmaningar för den byggda miljön på nya och ansvarsfulla sätt.

We shape the architects and civil engineers of the future. Through education and research in engineering and social science, architecture and humanities, we develop knowledge and solutions for the benefit of a sustainable society.

We work with new solutions for what you see, and what you don't see but experience, use and depend on in your home and in the built environment surrounding you. From underground structures, waste, water, sewage and indoor environment to transport systems, infrastructure and planning & design of buildings and cities. Our ambition is to inspire and motivate the addressing and solving of global, societal challenges for the built environment in new and responsible ways.

    Sensitivity analysis of clogged stormwater inlets in a 1D-2D hydrodynamic stormwater model - Case study of Uppsala

    Pluvial flooding caused by cloudburst is predicted to increase due to climate change and the preconditions for flooding changes due to urbanization. The municipalities in Sweden are responsible to assess what land use an area is appropriate for and 1D-2D hydrodynamic stormwater modelling is one tool that can be used to assess this. In practice, it is not rare that debris flushes towards stormwater inlets when raining. The debris can cause clogging of the inlets and reduce its capacity. This thesis has researched through a survey the working method regarding consideration of clogged stormwater inlets of limited number of consultants in Sweden. This thesis also evaluated the effect of clogged stormwater inlets and reduced capacity in a 1D-2D hydrodynamic stormwater model. A model built in MIKE+ of Uppsala in Sweden was used. To represent clogged stormwater inlets the capacity was reduced with a clogging factor affecting the discharge coefficient of the 1D-2D couplings of the model. Four simulations were done with four different clogging factors based on literature research and the survey regarding consultants working method. The responses of the survey presented that there is no common working method regarding if and how clogged stormwater inlets should be considered based on the group of consultants that answered the survey. A sensitivity analysis of the four simulations were made considering interaction volumes between the 1D collection system model and the 2D overland model, maximum water depth, water level and the discharge to surface in three nodes within the research area. The analysis concluded that the interaction volume from 1D to 2D is more affected by increasing clogging factor than the interaction volume from 2D to 1D. The extent and maximum water depth in the simulations are affected by the change of clogging factor but not largely. The analysis also concluded that the discharge in nodes is affected differently but the water level in nodes is not affected to a large extent by reducing capacity due to clogged stormwater inlets.
