ABSTRACT
The explicit formulation of urban growth projections is often neglected or rendered as an issue that in terms of complexity is regarded intractable. Nevertheless, the impacts of urban growth as a driver for increasing climate related impacts are widely accepted, especially in relation to flood risk. Only if urban growth scenarios are geographically bounded, they can express both the urban differentiation within and across cities as well as their interaction with coastal, fluvial and pluvial floods. Furthermore, better insight might be gained in how the contribution of urban growth to future flood risk compares to the projected impacts of climate change. Within the scope of riverine flooding, the available data is typically scattered over many projects, agencies and scale levels. The level-of-detail that is customary for stormwater modelling, which often is limited to drainage units, is therefore only rarely found for flood assessments of riverine flooding. The chapter also presents an overview of the key concepts discussed in this book.
