Abstract: | Climate change has altered locally single-type disasters to large-scale compound disasters because of increasing intensity
and frequency of extreme rainfall events. The compound disasters can combine small-scale floods, debris flows, shallow landslides,
deep-seated landslides, and landslide lakes into a large-scale single disaster event. Although simulation models and evaluation
tools are available for single-type disasters, no single model is well developed for compound disasters due to the difficulty
of handling the interrelationship between two successive single-type disasters. This study proposes a structure for linking
available single-type simulation models to evaluate compound disasters and provides a useful tool of decision making for warning
and planning of disaster reduction. |
