Integrated Urban Water Modelling - Past, Present, and Future

The technical and practical challenges of implementing the Integrated Urban Water Management paradigm provide the setting for the IUWM modelling review presented in this paper, which presents the findings of a review of the current "state-of-the-art" in IUWM modelling. It was found that in recent years there have been significant advances in the development of IUWM modelling tools, and a growing body of knowledge of the scientific and technical challenges of IUWM modelling. However, there are still sizable gaps in modelling capacity and in the knowledge underpinning the models, which require concerted research effort to adequately address. This paper discusses the background, features, and shortcomings of current IUWM modelling, and proposes directions for future research.
