  1. 11. Hybrid Rainfall Estimates from Satellite, Lightning and Ground Station Data in West Africa

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Henrik Enbäck; Charlotta Eriksson; [2015]
    Nyckelord :rainfall estimates; West Africa; lightning; satellite; nederbördsestimat; Västafrika; blixtar; satellit;

    Sammanfattning : Most of the working population in Ghana are farmers. It is of importance for them to know where and when precipitation will occur to prevent crop losses due to droughts and floodings. In order to have a sustainable agriculture, improved rainfall forecasts are needed. One way to do that is to enhance the initial conditions for the rainfall models. LÄS MER

  2. 12. Snowmelt and runoff assessment of Talas River Basin using remote sensing approach

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

    Författare :Hammad Javid; [2014]
    Nyckelord :Talas River; remotely sensed precipitation; TRMM; GPCC; MODIS; Chu-Talas River Basin; transboundary rivers; Central Asia; Physical Geography and Ecosystem Science; Earth and Environmental Sciences;

    Sammanfattning : Transboundary river basins provide inhabitance and water resources to millions of people around the globe and they are a source of dispute among neighbor countries also. This thesis focuses on the snow melt and runoff modeling of a small transboundary river, Talas; using a physically distributed rainfall-runoff model, TOPKAPI-ETH. LÄS MER

  3. 13. Assessment of spatio-temporal patterns of NDVI in response to precipitation using NOAA-AVHRR rainfall estimate and NDVI data from 1996-2008, Ethiopia

    Master-uppsats, Institutionen för naturgeografi och kvartärgeologi (INK)

    Författare :Getahun Tadesse Kabthimer; [2012]
    Nyckelord :NOAA AVHRR; NDVI; rainfall estimates; land cover classes.;

    Sammanfattning : The role of remote sensing data for monitoring different parameters in the study of ecosystems has been increasing. Particularly the development of different indices has played a great role to study the properties of vegetation and vegetation dynamics in large countries. LÄS MER

  4. 14. Size, temporal and spatial dynamics of a natterjack toad (Bufo calamita) population in Scania

    Master-uppsats, Lunds universitet/Examensarbeten i biologi

    Författare :Kirsten Persson; [2012]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : Abstract The breeding season of the natterjack toad (Bufo calamita Laurenti 1768), a „prolonged breeder“, lasts up to three months in southern Sweden. However, not all reproducing individuals are present at the breeding sites during the full time span. LÄS MER

  5. 15. Data resolution effects onwater resource planning andmanagement : The Kisumu – Lake Victoria region study

    Master-uppsats, Institutionen för naturgeografi och kvartärgeologi (INK)

    Författare :Alexander Koutsouris; [2009]
    Nyckelord :Kenya; Lake Victoria; Kisumu; water management; water planning; Irrigation; Climate change; Agriculture; rain water harvesting;

    Sammanfattning : In the Kisumu District, Kenya, unreliable rainfall pattern has been identified as one of the main causes for poverty in rural areas. The negative effects of such unreliable patterns could be mitigated through improved water resource management and planning. LÄS MER
