Dynamic population exposure modeling: Application of DynaPop-X for storm surge related coastal flood crisis management

In this paper we describe the application of a newly developed population dynamics model to time-dependent coastal flood exposure assessment at the French Atlantic coast. The DynaPop-X approach is largely top-down-driven, using national and regional data sources as primary disaggregation input. Modeled at 100m resolution and 1h temporal intervals dynamic population fluctuations such as commuting patterns and work hours as well as leisure activities are represented. Two selected municipalities in the study area are compared in terms of their population exposure profiles, highlighting stark differences in the temporal exposure peaks.
