Topic A

 

Sustainable Urban Storm Water Quality Management Supporting Blue-green Infrastructure

 

The project is rooted within sustainable water resources engineering research, but offers unique possibilities to collaborate beyond disciplinary boundaries to advance sustainable drainage system and constructed wetland system research. Flooding and water pollution affects sustainability and blue-green infrastructure in many ways. The effects come as a consequence of the damage done during flood events as well as point source and diffuse pollution. Economic and ecological losses occur both in the short-term and long-term. Flooding and aquatic pollution has a detrimental impact on water quality and the environment. Floods and pollution also destroy urban forms with social and cultural values. The project aims to increase sustainability of the built environment with respect to water quality management, protecting blue-green infrastructure from pollution with sustainable drainage systems and wetlands. The project will be centred around fieldwork on a case study either in Lund or Malmö. The study will (a) increase the understanding with respect to processes within sustainable storm water and wastewater treatment systems such as wetlands; (b) provide efficient methods to assess water quality risks; (c) find relationships between water quality risks and resilience as well as environmental and socio-economic parameters; and (d) find methods to improve water quality management and resilience.

Topic B

 

Urban Runoff Treated by Duckweed-planted Wetland Ponds and Recycled to Irrigate Red Clover

 

The project is embedded within sustainable urban water engineering research, but offers possibilities to collaborate beyond disciplinary boundaries to advance sustainable drainage system, constructed wetland system and agricultural water management research. Diffuse pollution affects blue-green infrastructure and agriculture in many ways. Economic and ecological losses occur both in the short-term and long-term. Aquatic pollution has a detrimental impact on water quality and the urban environment. The project aims to treat urban runoff collected by the Lake Lake (located on the LTH campus) by wetland ponds dominated by common duckweed. The outflow of the wetlands is recycled to irrigate red clover. Both plants can be used as fodder for farm animals. The project will involve laboratory work and nearby fieldwork. The project will (a) increase the understanding with respect to processes within sustainable storm water systems such as storm water ponds and experimental wetlands; (b) assess water quality improvements; and (c) evaluate the potential to recycle treated storm water in the agricultural sector.

Predicting dam failure risk for sustainable flood retention basins: a generic case study for the wider Lund area

 

Traditionally, dams are considered safe because they have been built according to high technical standards. However, many dams that were constructed decades ago do not meet the current state-of-the-art dam design guidelines. There is a need for a tool that could be used as an early warning system in times of heavy rainfall. Therefore, this study aims to provide a rapid screening tool for the assessment of sustainable flood retention basins (SFRB) to predict corresponding dam failure risks. A rapid expert-based assessment method for dam failure of SFRB supported by a model will be developed. Flood storage will be assessed for regional SFRB and the corresponding Dam Failure Risk will be evaluated for all dams across the wider Lund study area. The results may show that Dam Failure Risk can be estimated by using the variables such as Dam Height, Dam Length, Maximum Flood Water Volume, Flood Water Surface Area, Mean Annual Rainfall, Altitude, Catchment Size, Urban Catchment Proportion, Forest Catchment Proportion and Managed Maximum Flood Water Volume. Cross-validation for the model will be performed to assess if the tool is predicting variables well for new data sets. Spatial distribution maps showing dam failure risks of SFRB will be developed to support regional water resources decision-makers.

Rapid expert tool for different professions based on estimated ecosystem variables for retrofitting of drainage systems in Lund

 

There is a need for a geospatial decision support tool for different professions such as drainage engineers and urban planners, which is useful for a quick assessment of the potential of ecosystem services when retrofitting sustainable drainage systems (SuDS) in urban areas such as Lund. Therefore, the aim of this project is to develop an innovative rapid decision support tool based on ecosystem service variables for retrofitting of key SuDS techniques by different professionals such as drainage engineers, developers, ecologists, planners and social scientists. A transparent spreadsheet-based tool will be developed to support decision-makers in retrofitting of SuDS techniques that obtain the highest ecosystem service score for an urban site. This approach will be based on a novel ecosystem service philosophy adapted to SuDS rather than on traditional engineering judgement associated with variables based on quick community and environment assessments. This project will require considerable fieldwork within the wider Lund area.

Topic E

 

Sustainable Drainage System Site Assessment Method Using Urban Ecosystem Services

 

Some countries recently updated their approaches to sustainable drainage enhanced biodiversity and amenity objectives by incorporating the ecosystem approach and the ecosystem services concept. However, cost-effective and reliable methods to appraise the biodiversity and amenity values of potential sustainable drainage system (SuDS) sites and their surrounding areas are still lacking, as is a method to enable designers to distinguish and link the amenity and biodiversity benefits that SuDS schemes can offer. Therefore, this project aims to propose two ecosystem services- and disservices-based methods (i.e. vegetation structure cover-abundance examination and cultural ecosystem services and disservices variables appraisal) to aid SuDS designers to distinguish and link amenity and biodiversity benefits, and allow initial site assessments to be performed in a cost-effective and reliable fashion. Representative sites within Lund will be selected to test the two methods. Amenity and biodiversity will be assessed and habitat for species, carbon sequestration, recreation and education ecosystem services scores will be produced, which will support SuDS retrofit design decision-making. The focus will be on large vegetated SuDS sites with permanent aquatic features, which are likely to be most capable of enhancing biodiversity- and amenity-related ecosystem services. The link between habitat for species and recreation ecosystem services will be assessed. The findings should enable future SuDS retrofit designs to be more wildlife friendly and socially inclusive.
