This paper focuses on the spatial distribution of the dominant and relevant benefits of urban flood management based on context‐ and location‐specific evaluations. We explore the conceptual rationale and describe a detailed methodology for assessing the benefit profile , benefit intensity , and comment on benefit dependencies arising from urban flood management practices that utilise green infrastructure. A case study is described which demonstrates the application of the concepts in Portland, Oregon, USA. A Geographic Information System approach is developed to evaluate some of the multiple benefits of the East Lents Floodplain Restoration Project. Results are presented in the form of a comparative benefit profile, and a spatially distributed benefit intensity. The paper concludes with the implications of the methodology for future multiple benefit evaluation of urban drainage and flood management systems.
