  2. 1. Advanced Remote Sensing Precipitation Input for Improved Runoff Simulation : Local to regional scale modelling

    Author : Seyyed Hasan Hosseini; Avdelningen för Teknisk vattenresurslära; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydrology; Precipitation; Rainfall; Satellite; Runoff; Streamflow; Rainfall-runoff modelling; X-band weather radar; GPM-IMERG; MODIS Terra;

    Abstract : Accurate precipitation data are crucial for hydrological modelling and rainwater runoff management. Precipitation variability exists through a wide range of spatial and temporal scales and cannot be captured well using sparse rain gauge networks. READ MORE

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

    Author : Shimelis Gebriye Setegn; Bijan Dargahi; Nicola Fohrer; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; 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

  5. 3. Dissolved organic carbon in tropical watersheds : Linking field observation and eco-hydrological modelling

    Author : Fabien Rizinjirabake; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dissolved organic carbon DOC ; Rwanda; Land use land cover variability; Climate variability and change; Rukarara River Watershed; eco-hydrological modelling; field observation;

    Abstract : Dissolved organic carbon (DOC) is a general description of the organic material dissolved in water. DOC is an important source of energy, carbon, and nutrient transfers from terrestrial to aquatic ecosystems. The export of DOC into aquatic ecosystems may contribute to the carbon balance of terrestrial ecosystems and to water degradation. READ MORE

  6. 4. Hydraulic- hydromorphologic analysis as an aid for improving peak flow predictions

    Author : Anna Åkesson; Anders Wörman; Göran Lindström; Rolf Larsson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydrological modelling; peak flow predictions; distributed routing; parameterisation; stage-dependency; Hydrology; Hydrologi;

    Abstract : Conventional hydrological compartmental models have been shown to exhibit a high degree of uncertainty for predictions of peak flows, such as the design floods for design of hydropower infrastructure. One reason for these uncertainties is that conventional models are parameterised using statistical methods based on how catchments have responded in the past. READ MORE

  7. 5. Peakflow response of stream networks : implications of physical descriptions of streams and temporal change

    Author : Anna Åkesson; Anders Wörman; Alberto Viglione; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Streamflow routing; peakflow predictions; parameterization; hydrological response; stage-dependency; flooded cross-sections; stream networks; backwater effects; temporal change; land use change; Civil and Architectural Engineering; Byggvetenskap;

    Abstract : Through distributed stream network routing, it has quantitatively been shown that the relationship between flow travel time and discharge varies strongly nonlinearly with stream stage and with catchment-specific properties.Physically derived distributions of water travel times through a stream network were successfully used to parameterise the streamflow response function of a compartmental hydrological model.
