The Generation of Flood Damage Time Sequences

A new framework for flood damage assessment considering the within-event time evolution of hazard, exposure, and vulnerability

“…This is because an exposed item has an initial resistance that progressively reduces; in fact, with the damaging process progressing, exposed objects weaken and hence become more susceptible to being damaged. On the contrary, at the later stage of the process, damaging slows down and the maximum damage is reached gradually (Breaden, 1971); at this stage, the damaging rate becomes nearly proportional to the undamaged fraction of the objects effectively exposed to the action of floodwaters, V -D (Fig. 1), scaled by the relative potential damage, V. Mathematically, this behaviour can be described by the following equation…”
