Abstract: In the last decade damaging floods have affected many European cities including both Copenhagen and other major Danish cities. As an effect hereof the concept of integrated resilient water management is on the political agenda and climate adaptation plans are required for all Danish municipalities. An emerging area within the climate change debate addresses the quantification of natural climatic variations. Recent studies show profound multi-decadal oscillations in extreme rainfall over Europa including Denmark. The present study focuses specifically on the variation of historical design values for urban drainage design in Denmark. It is shown that these exhibit a similar pattern of variation. The analysis also covers Danish and European legislation on water management, concluding that the main directives on protection of the aquatic environment were adopted during periods of few extreme events. This illustrates the importance of the natural variation as a driver for the development of urban design practice and ranks it alongside technological and scientific advances. Therefore it is highly relevant to incorporate the knowledge on the natural variation in the concept of resilient water management but also in future research strategies
