  2. 1. Analytics-driven approaches supporting asset management of sanitary sewer networks

    Author : Emmanuel Okwori; Annelie Hedström; Maria Viklander; Marius Møller Rokstad; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Data-driven; Decision Support; Network Robustness; VA-teknik; Urban Water Engineering;

    Abstract : Sewer blockages can cause overflows and flooding, with consequences such as damage to property and environmental pollution, risks to public health and economic loss. Despite the causes being understood, blockages in sewer networks may occur unpredictably. READ MORE

  4. 2. Future trends in urban stormwater quality : effects of changes in climate, catchment characteristics and processes and socio-economic factors

    Author : Matthias Borris; Lian Lundy; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Abstract : Climate change and progressing urbanization cause numerous environmental concerns, including the impacts on urban drainage. Such impacts were addressed during the last two decades with focus on hydraulic overloading of drainage systems and the means of overload remediation by stormwater management. READ MORE

  5. 3. Environmental aspects of coal mine drainage: a regional study of Moatize in Mozambique

    Author : Estevao Pondja; Avdelningen för Teknisk vattenresurslära; []

    Abstract : Mozambique is one of the largest coal producers in Africa. Extraction of the coal is carried out in the Moatize district of the Tete province in the center of the country. A surface mining technique is used to extract the coal below ground level. READ MORE

  6. 4. Water and sediment quality of urban water bodies in cold climates

    Author : Ralf Rentz; Stefan Karlsson; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Abstract : The aim of this study was to investigate and quantify pollution impact on urban waterbodies in cold climates and to find out which complex processes and influencing factors causetrapping or spread of pollutants. In order to do that water, sediment and porewater samplesfrom bays and stormwater ditches in Luleå, northern Sweden, and from an artificialstormwater pond in Sollentuna, south-central Sweden, were analysed for LOI, trace metalsand PAHs.

  7. 5. Studies of an elusive element : processes that influence the net retention of mercury in lake sediments and peatlands

    Author : Johan Rydberg; Richard Bindler; Carl Lamborg; Umeå universitet; []
    Keywords : Mercury; retention; lake sediments; peatlands; environmental archives; sedimentation; diagenesis; vegetation; permafrost; Environmental Science; miljövetenskap;

    Abstract : Because of its toxic nature mercury is a threat to both wildlife and human health, and thus, it is an element of concern in the environment. Currently much of the mercury emitted to the atmosphere is derived from anthropogenic sources – both direct emissions and re-emission of already deposited anthropogenic mercury. READ MORE
