  1. 1. Stormwater Ponds for Pollution Reduction

    Författare :Thomas Pettersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; suspended solids; reduction; pollution; stormwater pond; flow modelling; FEM; field measurements; heavy metals; nutrients;

    Sammanfattning : Stormwater transports particulate-bound and soluble pollution from urban areas to receiving waters during rain events. Measurements have shown that open detention ponds, originally used for flood control, effectively reduce stormwater pollutant load and have therefore been increasingly used for stormwater treatment.

  3. 2. Contribution of stormwater ponds for road runoff to aquatic biodiversity

    Författare :Zhenhua Sun; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; road salt; stormwater ponds; water quality; sediments; road runoff; metals; pond size; aquatic biodiversity;

    Sammanfattning : 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. LÄS MER

  4. 3. Reducing Stormwater Pollution - Performance of Retention Ponds and Street Sweeping

    Författare :Jonas German; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; urban runoff; street sweeping; removal processes; treatment; removal efficiency; sediment; stormwater; BMP; modelling; pond;

    Sammanfattning : Stormwater, in this study defined as surface runoff in urban areas, is known to transport large quantities of toxic substances to receiving waters. Therefore different practices to treat stormwater have been proposed. In Sweden retention ponds have become a common treatment method during the past decade. LÄS MER

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

    Författare :Zhenhua Sun; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  7. 5. Floating treatment wetlands for stormwater management : Plant species selection and influence of external factors for heavy metal and chloride removal in a cold climate

    Författare :Maria Schück; Maria Greger; Hans Brix; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Floating treatment wetlands; Phytodesalination; Rhizofiltration; Phytoremediation; Stormwater; Heavy metals; Chloride; Plant traits; Carex riparia; Carex pseudocyperus; Phalaris arundinacea; Flytande våtmarker; dagvatten; tungmetaller; klorid; fytoremediering; slokstarr; rörflen; jättestarr; växtfysiologi; Plant Physiology;

    Sammanfattning : Stormwater, which consists of rainwater and snowmelt, often contains pollutants from vehicle traffic, building materials, and industries. These pollutants include chloride and heavy metals, which can cause several environmental issues, such as being toxic to biota at elevated concentrations. LÄS MER
