2. 1. 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.

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. Permafrost Groundwater Dynamics : Modeling of vertical and lateral flows in the active layer across multiple scales

   Author : Alexandra Hamm; Andrew Frampton; Peter Kuhry; Jeffrey McKenzie; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; permafrost; climate change; numerical modeling; hydrogeology; groundwater; naturgeografi; Physical Geography;

   Abstract : Hydrological processes in the Arctic are profoundly influenced by the presence of permanently frozen ground, known as permafrost. Conversely, permafrost is greatly affected by hydrological changes resulting from climate change. READ MORE

6. 4. 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 : 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

7. 5. Peatland dynamics in response to past and potential future climate change : A regional modelling approach

   Author : Nitin Chaudhary; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; PEATLANDS; PERMAFROST; Carbon accumulation; Microtopography; LPJ-GUESS; Earth system models;

   Abstract : The majority of the northern peatlands developed during the Holocene as a result of a positive mass balance between net primary productivity (NPP) and heterotrophic decomposition rates. Over that time they have sequestered a huge amount of carbon in terrestrial ecosystems. READ MORE
