Abstract For assessing the performance of urban infrastructures over long time horizons of 30–90 years, urban development models are desirable that explicitly represent the physical layout of the city, while confining model complexity to an appropriate level. Such models have recently appeared in the literature, but parameters were often defined ad-hoc or without documentation. This paper presents approaches to derive important parameters for such models based on commonly available data. We appl...

Cities increasingly use real-time control of combined sewer systems and green infrastructure to decrease emissions to surface waters, and incorporate infrastructure into the urban landscape to reduce flooding from short, intense rainfall events called cloudbursts, which can cause flash flooding. Inspired by the ‘smart cities’ agenda, we propose the use of integrated stormwater inflow control to dynamically activate cloudburst conveyance infrastructure in the urban landscape as well as green stor...

Abstract. Urban development models typically provide simulated building areas in an aggregated form. When using such outputs to parametrize pluvial flood risk simulations in an urban setting, we need to identify ways to characterize imperviousness and flood exposure. We develop data-driven approaches for establishing this link, and we focus on the data resolutions and spatial scales that should be considered. We use regression models linking aggregated building areas to total imperviousness, and...

Abstract Floods are a constant threat to ecosystems, humans, infrastructure and assets. The combination of increased urbanization and rising sea levels makes it a concern of increasing societal importance. This study offers a new perspective on environmental impact assessment of flood related repairs related to a single-family residence using life cycle assessment. A typical European house built in the 2010's is modelled in the life cycle assessment framework with focus on items damaged by a flo...

Abstract The implementation, operation and decommissioning of stormwater management systems causes environmental damage, while at the same time reducing pollutant loads in receiving waters by treating stormwater. The focus in research has been either on assessing impacts caused by stormwater infrastructure, or risks associated with stormwater discharges, but rarely have these two sources of environmental impacts been combined to allow a comprehensive environmental evaluation of stormwater manage...

Abstract Stormwater carries pollutants that potentially cause negative environmental impacts to receiving water bodies, which can be quantified using life cycle impact assessment (LCIA). We compiled a list of 20 metals, almost 300 organic compounds, and nutrients potentially present in stormwater, and measured concentrations reported in literature. We calculated mean pollutant concentrations, which we then translated to generic impacts per litre of stormwater discharged, using existing LCIA char...
