    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Jonas Linnersund; Erik Mårtensson; [2008]
    Nyckelord :Fysisk geografi; climatology; cartography; Environmental studies; Miljöstudier; wind; water balance; tide; sediment transport; salt balance; renewal time; net intertidal volume; finite element; internal circulation; ADCIRC; CMS-Flow; Bardawil Lagoon; Physical geography; pedology; geomorphology; geomorfologi; marklära; kartografi; klimatologi; Technological sciences; Teknik; Earth and Environmental Sciences; Technology and Engineering;

    Sammanfattning : Bardawil Lagoon, a natural lagoon located on the northern coast of the Sinai Peninsula, Egypt, there are three inlets of which two are man-made connecting the lagoon with the Mediterranean Sea. The inlets are subjected to changes in morphology, due to sediment transport, over time and this may lead to degrees of closure of either inlet. LÄS MER

  3. 2. Estimation of Evapotranspiration through remote sensing. Comparison between three different resolution sensors at Barrax field, Spain.

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :John Diego Sierra Torres; [2008]
    Nyckelord :geomorphology; Physical geography; Evapotranspiration and semote sensing; S-SEBI Model; Water balance; Environmental Satellite images applications; Environmental studies; Miljöstudier; Natural science; climatology; cartography; Naturvetenskap; Hydrogeology; geographical and geological engineering; Hydrogeologi; teknisk geografi; teknisk geologi; pedology; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi; Earth and Environmental Sciences;

    Sammanfattning : Nowadays importance of water balance regarding measurements and water cycle pathways are of prime interest in a new perspective. Global issues, like Earth warming, or regional planned uses of water, e.g. irrigation, demand an increase in accuracy and coverage of different components of the water balance. LÄS MER

  4. 3. Seasonal Closure of Chilaw Inlet in Sri Lanka -Physical Processes and Mathematical Modelling-

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Alexandra Angelbratt; Jon Klyft; [2007]
    Nyckelord :geomorfologi; Fysisk geografi; climatology; Chilaw inlet; Spit Evolution; Tidal inlets; Inlet Closure; klimatologi; kartografi; Sediment Transport; Mathematical Model; Physical geography; geomorphology; cartography; pedology; marklära; Technological sciences; Teknik; Earth and Environmental Sciences; Technology and Engineering;

    Sammanfattning : Chilaw inlet, with the affiliated lagoon, is located on the west coast of Sri Lanka about 120 km north of the capital Colombo. Each year during the summer monsoon, which lasts from May to September, the inlet closes due to a sand spit forming across the inlet. LÄS MER
