Abstract
We built an R-version of the EmiStat model which we call EmiStatR. EmiStatR can easily do uncertainty propagation analysis because it can make use of extensive functionalities of R. We propose an uncertainty framework which we apply to the EmistatR in a case study to analyse uncertainty propagation associated to rainfall and impervious areas.

Most urban drainage models do not pay attention to uncertainty propagation. In particular, commercial software packages as used in engineering practice typically ignore uncertainties due to lack of user-friendly software implementations and tools. However, uncertainties can be substantial and ignoring these may affect decision making. In particular, end users should be aware of uncertainties so that they can take more robust decisions. Thus, research into uncertainty propagation in urban drainage modelling and development of operational systems that can trace the propagation of uncertainties is needed. We have made a contribution to this effort by proposing an uncertainty propagation framework for urban drainage modelling and applying first use case with the EmiStatR model.
