  1. 1. Scenariohantering med parametrisk design i planeringsprocessen

    Master-uppsats, Lunds universitet/Lantmäteri (CI); Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Beatrice Ekström; David Andersson; [2023]
    Nyckelord :Naturgeografi och ekosystemvetenskap; parametrisk design; scenariohantering; stadsmodell; planeringsprocessen; solinstrålningsanalys; 3CIM; Technology and Engineering;

    Sammanfattning : In line with an increasing population and the ongoing digitization process, there is a need for an effective planning process. In Sweden, there are both national and international goals that concern this. Zoning plans are an important tool for regulating the planning process. LÄS MER

  3. 2. Ajourhållning av en stadsmodell med multipatch i LOD2.2 : Utveckling av Karlstads kommuns ajourhållning av stadsmodellen genom att rita upp geometrin i geografiska CAD-program

    M1-uppsats, Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)

    Författare :Emil Dovrén; [2023]
    Nyckelord :3D-byggnader; Multipatch; ArcGIS Pro;

    Sammanfattning : Karlstad municipality owns an urban model made by external companies. The municipality wants to be able to update the model on its own. Today the municipality update the model using UAV photos processed in Agisoft Metashape. This study aims to investigate the option of creating 3D objects with ArcGIS Pro and photos of the building.

  4. 3. 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

  5. 4. 3D stadsmodeller för mindre kommuner - vad är behoven och vilka standarder krävs?

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap; Lunds universitet/Lantmäteri (CI)

    Författare :Andreas Ahlström; [2022]
    Nyckelord :3D; stadsmodell; 3D stadsmodell; standard; kommun; 3CIM; Nationella specifikationer; CityGML; CIM; Technology and Engineering; Earth and Environmental Sciences;

    Sammanfattning : A 3D city model is commonly used by Swedish municipalities in for example city planning or building permit assessment. There are however various kinds of 3D city models of which some are described in this report, for example a semantic 3D object model, mesh model, CIM model or a digital twin model. LÄS MER

  7. 5. How design storms with normally distributed intensities customized from precipitation radar data in Sweden affect the modeled hydraulic response to extreme rainfalls

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

    Författare :Daniel Elfström; Max Stefansson; [2021]
    Nyckelord :cloudbursts; cloudburst mapping; spatial rain variation; pluvial flooding; hydraulic response; Swedish precipitation radar data; idealized urban catchment; hydrodynamic modeling; skyfall; skyfallskartering; gaussisk regnfördelning; spatial regnvariation; pluvial översvämning; hydraulisk respons; svensk nederbördsradardata; idealiserat urbant avrinningsområde; hydrodynamisk modellering;

    Sammanfattning : Intense but short-term cloudbursts may cause severe flooding in urban areas. Such short-term cloudbursts mostly are of convective character, where the rain intensity may vary considerably within relatively small areas. Using uniform design rains where maximum intensity is assumed over the whole catchment is common practice in Sweden, though. LÄS MER
