  1. 1. Satellite derived data to support flood modelling : An application to the Po River

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

    Författare :Victor Alejandro Ortiz Peña; Milos Dinic; [2018]
    Nyckelord :Hydraulic Modelling; Flood Modelling; HEC-RAS; Mannings Coefficient; DEM; LiDAR; SRTM; Virtual Stations;

    Sammanfattning : Satellite derived data has become an essential input in hydraulic modelling. Digital ElevationModels (DEMs) derived from different sources through remote sensing techniques have become a powerful tool for poorly gauged regions. LÄS MER

  3. 2. Flood Risk Mapping in Africa: Exploring the Potentials and Limitations of SRTM Data in the Lower Limpopo, Mozambique

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Paulina Bastviken; [2016]
    Nyckelord :Flood inundation modelling; Africa; SRTM; LISFLOOD-FP; quality analysis; Översvämningsmodellering; Afrika; SRTM; LISFLOOD-FP; kvalitetsanalys;

    Sammanfattning : Many regions in Africa are presently faced with an increasing flood risk due to impending climate change and population growth. One useful mitigation strategy to decrease this risk would be to map it, so that urban planning, warnings systems and emergency response subsequently could be designed to reduce societal vulnerability.

  4. 3. Quantifying terrain factor using GIS applications for real estate property valuation

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Dahlia Mudzaffar Ali; [2016]
    Nyckelord :digital elevation model DEM ; GIS; geography; physical geography; property valuation; Earth and Environmental Sciences;

    Sammanfattning : This thesis studies the use of GIS applications to derive adjustment figures for the terrain factor in property valuation tasks. It aims at suggesting a quantitative approach alternative to evaluate the terrain factor as opposed to traditional methods and current industry practices where terrain is qualitatively judged based on visual observation at site and subjected to individual opinion.

  5. 4. Development of a Flood Model Based on Globally-Available Satellite Data for the Papaloapan River, Mexico

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Janis Kreiselmeier; [2015]
    Nyckelord :Flood inundation modelling; shuttle radar topography mission SRTM ; light detection and ranging LiDAR ; LISFLOOD-FP; Remote sensing; Översvämningsmodellering; shuttle radar topography mission SRTM ; light detection and ranging LiDAR ; LISFLOOD-FP; Fjärranalys;

    Sammanfattning : Flood inundation modelling is highly dependent on an accurate representation of floodplain topography. These  remotely  sensed  accurate  data  are  often  not  available  or  expensive,  especially  in  developing countries. LÄS MER
