    Sammanfattning : Water constraints for humans and nature are gaining more and more public attention as a critical environmental dilemma that needs to be addressed. When aquifers and rivers are running dry, the debate refers to an ongoing “world water crisis”. LÄS MER

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

    Författare :Shimelis Gebriye Setegn; Bijan Dargahi; Anders Wörman; C. Green Rossi; KTH; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 3. Green Urban Drainage Infrastructure : Hydrology and Modelling of Grass Swales

    Författare :Hendrik Rujner; Maria Viklander; Günther Leonhardt; Jiri Marsalek; Barraud Sylvie; Luleå tekniska universitet; []

    Sammanfattning : The management of urban runoff has evolved along with the advancement of understanding of runoff environmental impacts. Besides the impacts on water quality in the receiving waters, the impacts on the urban hydrologic regime include reduced infiltration by the sealing of pervious land, reduced evapotranspiration by removal of vegetation, and the resulting increase of stormwater runoff peaks and volumes causing flooding, and ultimately degradation of receiving waters.

  4. 4. Beneficial Use of Stormwater - Opportunities for urban renewal and water conservation

    Författare :Edgar Villarreal-Gonzalez; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; soil mechanics; Väg- och vattenbyggnadsteknik; offshore technology; hydraulic engineering; Civil engineering; water conservation; rainwater collection; Best Management Practices; Urban stormwater; green-roofs; open drainage systems;

    Sammanfattning : This thesis investigates the beneficial use of stormwater in Swedish urban environments. The focus has been on open stormwater systems for source control, as well as rainwater collection systems. To analyse the implementation of open stormwater systems, two case studies are presented: Augustenborg in Malmö and Bäckaslöv wetland in Växjö. LÄS MER
