The research presented in this paper proposes a novel methodology for modelling the
impacts of floods on traffic. Often flooding is a complex combination of various causes
(coastal, fluvial and pluvial). Further, transportation systems are very sensitive to external
disturbances. There is insufficient knowledge on the interactions in these complex and
dynamic systems. This paper proposes a methodology for integrating a flood model (MIKE
Flood) and a traffic model (SUMO). Traffic on inundated roads will be interrupted or delayed
according to the manner of flood propagation. As a consequence, some trips will be
cancelled or rerouted and other trips will be indirectly affected. A comparison between the
baseline and a flood scenario yields the impacts of that flood on traffic, estimated in terms
of lost business hours, additional fuel consumption, and additional CO2 emissions. The
outcome suggests that the proposed methodology can help to quantify the flood impact on
transportation.
