  1. 1. Modelling Hydrological and Hydrodynamic Processes in Lake Tana Basin, Ethiopia

    Author : Shimelis Gebriye Setegn; Bijan Dargahi; Nicola Fohrer; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Lake Tana; Climate Change; SWAT; Hydrological Modeling; Hydrodynamic; GEMSS; MCE; Streamflow; Sediment yield; Hydrology; Hydrologi; Water engineering; Vattenteknik;

    Abstract : Lake Tana Basin is of significant importance to Ethiopia concerning water resources aspects and the ecological balance of the area. The growing high demands in utilizing the high potentials of water resource of the Lake to its maximal limit, pictures a disturbing future for the Lake. READ MORE

  2. 2. Modeling flow and sediment transport in water bodies and watersheds

    Author : Muluneh Admass Mekonnen; Bijan Dargahi; Anders Wörman; Hans Bergh; Edward Buchak; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bed load transport model; ECOMSED; Hydrology; Hydrodynamics; Spectral Analysis; SWAT; Water engineering; Vattenteknik;

    Abstract : The research focus is on the various modeling aspects of flow and sediment transport in water bodies and watersheds. The interaction of flow with a mobile bed involves a complex process in which various turbulent scales characterized by coherent structures cause a chaotic sediment motion. READ MORE

  3. 3. Hydrological and sediment yield modelling in Lake Tana Basin, Blue Nile Ethiopia

    Author : Shimelis Gebriye Setegn; Bijan Dargahi; Anders Wörman; C. Green Rossi; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; SWAT; Lake Tana; Blue Nile; hydrological modelling; watershed modelling; MCE; SUFI-2; GLUE; ParaSol; streamflows; sediment yield; erosion; water balance; model calibration; Hydrology; Hydrologi;

    Abstract : Land and water resources degradation are the major problems on the Ethiopian highlands. Poor land use practices and improper management systems have played a significant role in causing high soil erosion rates, sediment transport and loss of agricultural nutrients. So far limited meas-ures have been taken to combat the problems. READ MORE

  4. 4. Intensifying Agricultural Water Management in the Tropics : A cause of water shortage or a source of resilience?

    Author : Yihun Dile; Johan Rockström; Louise Karlberg; Mekonnen Gebremichael; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Water harvesting; Climate change; Climate variability; Multi criteria evaluation; SWAT; CN; sub-Saharan Africa; Upper Blue Nile; Lake Tana basin; naturresurshushållning; Natural Resources Management;

    Abstract : Frequent climatic shocks have presented challenges for rainfed agriculture in sub-Saharan Africa. Appropriate water management practices are among the solutions to the challenges. The role of water harvesting in achieving sustainable agricultural intensification and specified resilience was explored. READ MORE

  5. 5. Modelling water resources despite data limitations in Tanzania’s Kilombero Valley

    Author : William Senkondo; Steve W. Lyon; Chong-Yu Xu; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Hydrological modelling; Recession analysis; Remote sensing; Water resources; Evapotranspiration; Transmissivity; SWAT model; Kilombero Valley; naturgeografi; Physical Geography;

    Abstract : Water is a vital resource for survival on the Earth. Sustainable management of water resources is therefore required for the wellbeing of present and future generations. A cornerstone of water resources management is scientific guidance supported by relevant data (in terms of quantity and quality). READ MORE
