A decision support model for the optimal siting and sizing of storage units in stormwater drainage systems

Abstract

Climate change and urbanization are the main factors involved in increasing cities' susceptibility to flood events. Extreme rainfall events are occurring more often due to climate change and this, together with the effect of impermeable surfaces, means that the runoff increases. Consequently, the existing stormwater drainage systems need to be adapted. One solution to adapt these systems would be to include infrastructure elements, such as storage units, in the hydraulic network to control flow and reduce peak flows.
