  1. 1. Remote Sensing Based Pre-Season Yellow Rust Early Warning in Oromia, Ethiopia

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

    Författare :Chinatsu Endo; [2021]
    Nyckelord :yellow rust; modeling; prediction; early warning; remote sensing; geography; geographical information systems; GIS; Agriculture and Food Sciences; Earth and Environmental Sciences;

    Sammanfattning : Yellow rust (Puccinia striiformis f. sp. Tritici) is a crop disease caused by a fungus that regularly infects wheat and causes yield loss in Ethiopia. The disease has a significant impact on the country’s crop production, food security, health, and socioeconomic well-being. LÄS MER

  3. 2. Sea Level Rise Vulnerability Assessment for Abu Dhabi, United Arab Emirates

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

    Författare :Marwa al Kabban; [2019]
    Nyckelord :Physical Geography and Ecosystem analysis; GIS; Sea Level Rise; Vulnerability Assessment; Modelling Sea Level Rise; Impacts Assessment of Sea Level Rise; GIS application in Sea Level Rise; Disaster Risk Reduction DRR ; Government Information Sharing GIS ; ArcGIS Web App Builder Dashboard; Sea Level Rise Story Map; Earth and Environmental Sciences; Technology and Engineering;

    Sammanfattning : The phenomenon of global warming has become a fact, however; the uncertainty is about the magnitude and acceleration of its manifestations. Global mean sea level rise is one of the results induced by global warming and is happening with an undetectable accelerated pace. LÄS MER

  4. 3. Application of a new method to improve river cross sections derived from satellite images

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

    Författare :Elin Andersson; Sofia Hietala; [2018]
    Nyckelord :Cross Section; Slope Break; Po River; Hydraulic modelling; Hydrological modelling; Matlab;

    Sammanfattning : In hydrological and hydraulic modelling, river geometry is a crucial input data. Recent investigations have been looking at methods to improve the description of cross sections extracted by DEM derived by satellite images. LÄS MER

  5. 4. Potentialities of Unmanned Aerial Vehicles in Hydraulic Modelling : Drone remote sensing through photogrammetry for 1D flow numerical modelling

    Master-uppsats, KTH/Byggvetenskap

    Författare :Andrea Reali; [2018]
    Nyckelord :UAV; remote sensing; structure from motion; photogrammetry; 1D steady flow hydraulic numerical modelling; hydraulic modelling;

    Sammanfattning : In civil and environmental engineering numerous are the applications that require prior collection of data on the ground. When it comes to hydraulic modelling, valuable topographic and morphology features of the region are one of the most useful of them, yet often unavailable, expensive or difficult to obtain. LÄS MER

  7. 5. 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
