Frequently asked questions

What does a probabilistic assessment consider?

It examines occurrence likelihood and uncertain conditions in addition to scenario results. The appropriate approach depends on the assessment purpose.

Is an inundation map an exact prediction of damage?

It represents results under specified terrain, forcing and model assumptions. Those conditions and limitations must accompany its use in planning and safety review.
