Abstract:
Cities worldwide are facing different challenges based on the disruption of the natural water balance in urban areas. The implementation of nature-based solutions (NBS) for stormwater management helps to counteract these challenge as they provide multiple benefits. However, their integration into existing built-up areas is challenging. To identify suitable locations and select appropriate technologies various decision support tools have been developed. However, the existing decision support tools lack consideration of spatial framework conditions and a spatial approach to urban challenges. Therefore, this dissertation aims to develop methods for identifying priority locations for implementing NBS for stormwater management in built-up areas, considering spatial framework conditions and the spatial distribution of urban challenges for the prioritization of NBS implementation locations. The spatial framework conditions influence the feasibility of NBS implementation at a specific location. Therefore, methods for the analysis of the built environment and natural landscape features have been developed. The urban challenges determine the demand for NBS implementation at a specific location. Their consideration is based on method for the evaluation of urban drainage challenges and the spatial distribution of urban heat island and water pollution potential. The developed methods mainly take a citywide approach to facilitate the assessment of potential locations in larger areas. Thereby, they provide a basis for strategic planning for NBS implementation for stormwater management in urban areas. With the application of the developed methods into an integrative planning process transparent decision-making is achieved. In conclusion, it can be said that while additional research will be needed in the field, this dissertation provides a basis for integrating spatial framework conditions into the decision-making process of implementing NBS and prioritizing locations.
