Abstract
A research program in Denmark on statistical modelling of rainfall has resulted in a model for
regional distribution of rainfall extremes. The results show that extreme rainfalls critical to the hydraulic
function of urban drainage systems and the pollution discharge are subject to a significant regional variation
of extreme rainfalls throughout the country. This has implications for design and analysis of all practical
problems related to urban drainage, since the rainfall data so far recommended as input to engineering
analyses underestimates the problems. Consequently, the Danish Water Pollution Control Committee has
issued a statement recommending a new engineering practice. The dissemination of the research results
proved to be difficult due to lack of understanding of the concepts of the new paradigm by practitioners. The
traditional means of communication was supplemented by user-friendly spreadsheets and easy access to
rainfall data as well as giving courses on the new paradigm. This has eased the implementation of the new
concepts greatly.
