Agent?based simulator of dynamic flood?people interactions

This article presents a simulator for the modelling of two-way interactions between flooding and people. The links hydrodynamic model to pedestrian in single agent-based platform, Flexible Large-scale Agent Modelling Environment Graphical Processing Unit (FLAMEGPU). Dynamic coupling is achieved by simultaneous update exchange information across multiple agent types. Behavioural rules states agents are proposed account pedestrians' presence/actions in/to floodwater. These based on commonly used hazard rate (HR) metric evaluate risk people floodwater, considering two roles pedestrians: evacuees or responders action during before flood event, respectively. potential demonstrated case study flooded busy shopping centre scenarios: (a) evacuation (b) pre-flood intervention deploy sandbag barrier. scenario points changes floodwater hydrodynamics around congested areas, which either worsen (by 5–8%) lessen 25%) HR. demonstrates utility select an optimal barrier height number safe effective deployment. Accompanying details software accessibility provided.
