  1. 1. Remote Sensing of Cryospheric Surfaces : Small Scale Surface Roughness Signatures in Satellite Altimetry Data

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Petter Ideström; [2023]
    Nyckelord :Remote sensing; Altimetry; Arctic; Cryosphere; ICESat-2; Cryosat-2; Svalbard;

    Sammanfattning : The Arctic cryosphere is experiencing a higher rate of warming compared to the rest of the world due to Arctic amplification. As glacier elevation change provide reliable evidence of climate change it is routinely measured by satellite altimeters. LÄS MER

  3. 2. 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

  4. 3. Monitoring of Incomati River Basin with Remote Sensing

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Bijan Khalili; [2007]
    Nyckelord :Civil engineering; teknisk geografi; teknisk geologi; Radar Altimetry; Synthetic Aperture Radar; Remote Sensing; Optical method; hydraulic engineering; Water Resource; GIS; Landsat; Hydrogeology; Hydrogeologi; geographical and geological engineering; offshore technology; soil mechanics; Väg- och vattenbyggnadsteknik; Earth and Environmental Sciences; Technology and Engineering;

    Sammanfattning : Incomati river basin is located in the continent of South Africa and is shared between three countries of Republic of Mozambique, Republic of South Africa, and the Kingdom of Swaziland. Located in a water-stressed region and shared between three countries it has importance in both sociopolitical and water scarcity aspect. LÄS MER

  5. 4. Passive Aircraft Altimetry using GPS as a Bistatic Radar : A simulation model

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Anders Andersson; Daniel Hallgren; [2003]
    Nyckelord :Datorteknik; Bistatic radar; GPS; altimeter; passive; reflectivity; scattering; altimetry; Datorteknik;

    Sammanfattning : A common way to measure height in aerial vehicles is to use a radar height altimeter (RHM). Since the RHM transmits radar pulses that can be detected, a passive alternative would be desirable in military applications. LÄS MER
