  2. 1. Efficient Management of Water Utilities : Sustainability Analysis of Swedish Performance

    Author : Nasik Najar; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sustainability index; reinvestment; facilities status; climate adaptation and flood security; ; water utility in Sweden;

    Abstract : In Sweden, a sustainability index (SI) has been used since 2014 as an internal benchmark management tool to analyse and steer municipal water and wastewater (WW) activities toward sustainability. A consistent trend in national results from SI across all years is that while day-to-day operations are working well, there are deficiencies in strategies for long-term planning. READ MORE

  4. 2. The Ecological Role of Roadside Stormwater Ponds - Potential to Support Biodiversity

    Author : Zhenhua Sun; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Macroinvertebrates; Stormwater ponds; DNA metabarcoding; Sediments; High throughput sequencing; Road runoff; Water quality; Aquatic biodiversity;

    Abstract : The increased recognition that roads may impair the aquatic environment and ecosystems has led to a shift from conventional drainage systems toward blue-green solutions such as stormwater ponds. Research on blue-green stormwater solutions has until now mainly focused on water quantity and quality. READ MORE

  5. 3. Application of satellite data for investigation of water quality in coastal areas

    Author : Chuqun Chen; Avdelningen för Teknisk vattenresurslära; []
    Keywords : Atmospheric correction; Pearl River estuary; Daya Bay.; Numerical modeling; Chlorophyll-a; Water quality; Ocean color remote sensing; Gelbstoff;

    Abstract : The population growth in China together with the rapid industrialization and urbanization have increased the utilization of natural resources, leading to more waste being released to the environment. Thus, the environmental conditions have degraded in many regions to a point where environmentally related problems have become the main limiting factors for economical development and social progress.

  6. 4. Impacts of land use change on river streamflow and water quality in a semi-arid catchment : assessment of a catchment under rapid and uncontrolled urbanisation

    Author : Benjamin Gossweiler; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The ongoing degradation of water quality and streamflow in rivers and streams worldwide is mainly due to human action through global land use change, particularly urbanisation. Population growth and economic development are major drivers of urbanisation, which causes environmental problems such as high water demand and solid waste and wastewater generation. READ MORE
