1. 1. Hydrological modeling as a tool for sustainable water resources management: a case study of the Awash River Basin

   Författare :Selome M. Tessema; Berit Balfors; Ulla Mörtberg; Shimelis Gebriye Setegn; Steve W. Lyon; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hydrological characteristics; Distributed hydrological modeling; Rainfall-runoff correlation; Streamflow prediction; Sustainable water management; Awash River Basin; Hydrology; Hydrologi;

   Sammanfattning : The growing pressure on the world‘s fresh water resources is enforced by population growth that leads to conflicts between demands for different purposes. A main concern on water use is the conflict between the environment and other purposes like hydropower, irrigation for agriculture and domestic and industry water supply, where total flows are diverted without releasing water for ecological conservation.

4. 3. The role of roads on hydrological response : Modeling and assessment for Swedish watersheds

   Författare :Alireza Nickman; Per-Erik Jansson; Lars Rosen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GIS; Roads; Flooding; HEC-HMS; Sweden; Mark- och vattenteknik; Land and Water Resources Engineering;

   Sammanfattning : Understanding the role of road networks in alteration of hydrological responses is crucial for maintaining the accessibility and durability of road infrastructures. Road construction is one of the most common man made disturbances to a landscape. LÄS MER

5. 4. Spatiotemporal streamflow variability in a boreal landscape : Importance of landscape composition for catchment hydrological functioning

   Författare :Reinert Huseby Karlsen; Jan Seibert; Kevin Bishop; Thomas Grabs; Sarah E. Godsey; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; streamflow; catchment hydrology; boreal; water balance; spatiotemporal variability; landscape analysis; climate change; recession curve; Hydrology; Hydrologi;

   Sammanfattning : The understanding of how different parts of a landscape contribute to streamflow by storing and releasing water has long been a central issue in hydrology. Knowledge about what controls streamflow dynamics across landscapes can further our understanding of how catchments store and release water, facilitate predictions for ungauged catchments, and improve the management of water quality and resources.

7. 5. Sedimentological and Hydrological Investigation of Mosul Dam Reservoir

   Författare :Issa E Issa; Ian Foster; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Area-storage capacity curves; Area reduction method; Bathymetric survey; Losing storage capacity; Mosul dam; Reservoir bottom morphology; Reservoir sedimentation; Sediment trap efficiency; Useful life of dam; Soil Mechanics; Geoteknik;

   Sammanfattning : Reservoir sedimentation is the main problem that directly affects the performance of dams due to the reduction in the storage capacity of their reservoirs. Monitoring the storage capacity of reservoirs is an important issue for the planners, designers and operators of the dams. LÄS MER
