From the developer:
HYRISK implements a rational and practical strategy for assessing the relative
risk of scour failure for bridges with foundations subject to scour. The relative
risk of scour failure is calculated as the product of the cost associated with
failure and the probability of failure. The method is based on data contained in
the NBI database.
