The Dupuy catchment (Laferrere, Metropolitan Region of Buenos Aires) has suffered numerous floods in recent years. The frequency and magnitude of these events, coupled with the large number of people affected, has led to some community representatives organising themselves to collect flood records, increase awareness of the problem and push for solutions and mitigating actions. That campaign inspired the study of the flooding dynamics of the catchment, with the aim of developing simple tools for risk mitigation. To analyse the water dynamics in the catchment, a high‐resolution urban numerical model was implemented with the EPA‐SWMM software. Due to the lack of systematic observations of flow variables, the model was validated using data collected by the affected community itself. More than 500 simulations of different synthetic storms were run on a high‐performance computational cluster and analysed. These processed results, coupled with the observation of rainfall intensities during an event, may be used by the community and risk managers to reduce exposure and mitigate flood risk.
