  1. 16. Generation of urban runoff : Seasonal and climate change perspective

    Författare :Shahab Moghadas; Claes Hernebring; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Sammanfattning : Runoff generation in cold regions is characterized by snowmelt contributions to runoff during the periods of thawing and changing runoff patterns due to frozen ground. This thesis project aimed at addressing these challenges by advancing the procedures for winter urban runoff computations and the assessment of control measures during the winter/spring period, when the snowmelt and frozen soils dominantly impact runoff generation in the current and future climates.

  4. 18. Development of Decision Support Tools for Urban Water Supply Management in Uganda

    Författare :Frank Kizito; Roger Thunvik; Patrick Ogao; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Decision support systems; Participatory decision-making; Geovisualization; Non-revenue water; Geostatistics; Action research; Water engineering; Vattenteknik;

    Sammanfattning : In this study, five real-life problem situations were used to explore the challenges of developing and implementing decision support tools for management of an urban water utility in Uganda. The study sought to explore how the degree of adoption of formal decision support tools in practice, generally perceived to be low, could be improved. LÄS MER

  5. 19. Insufficient water supply in an urban area - case study : Tegucigalpa, Honduras

    Författare :Zairis Aida Coello Midence Balthasar; Jan-Erik Gustafsson; Berit Balfors; Mats Lannerstad; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; water supply; Honduras; SANAA; Tegucigalpa; water utility;

    Sammanfattning : Tegucigalpa, the capital of Honduras, has experienced an unsatisfied water demand during the last three decades. The state owned water utility in charge of the water supply of the country, SANAA, has faced this deficit by providing an intermittent water supply. LÄS MER

  7. 20. Urban water management : Modelling, simulation and control of the activated sludge process

    Författare :Mats Ekman; Bengt Carlsson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatic Control; Reglerteknik;

    Sammanfattning : During the last few decades, wastewater treatment processes in urban water management have become more and more efficient and complex. Several factors such as urbanization, stricter legislations on effluent quality, economics, increased knowledge of the involved biological, chemical and physical processes as well as technical achievements have been important incentives for the development of more efficient procedures for wastewater treatment plants.
