In the context of climate change and urbanisation, it is important to keep the capacity limits of existing drainage systems under continuous review. With regard to the increase in extreme weather events such as heavy rainfall and droughts in combination with increasing land sealing, coupled modelling offers a good opportunity to run through various future scenarios by changing influencing factors.
