A fragility curve represents the probability of failure over a range of elevation values at a specific location. The Fragility Curve Plugin allows the user to define fragility curves and sample the failure elevations randomly during a HEC-WAT Flood Risk Analysis (FRA) compute option.
The elevation of failure that is sampled becomes an output data location that can be linked by any other application in the program order. Fragility curves can be sampled every event, once a lifecycle, or once every realization.
