Abstract: Being risk defined as product of probability of occurrence by caused damage, urban floods have particularly high risk due to the damage they cause. This paper describes the methodology and presents results which have been obtained during a study to access urban flood risk in several Portuguese cities in context of climate change scenarios. The paper starts with a description of the methodology and considerations which have been used in order to integrate the storm water model SWMM with the distributed watershed model MOHID Land, using the open source library Open MI. This integrated model has been applied to several cities in order to access risk based on the damage caused by floods associated with different return periods. Results for the downtown of Lisbon, included in this paper, show the comparison of scenarios to mitigate flood risk for a 10-year return period.
