Hazard definition refers to the various factors that have contributed to the inundation extents that are the key outputs of this project.

Studies use differing approaches in determining what constitutes a hazard zone. After consultation with the PCG and technical reviewers, the inundation hazards have been defined in Table 4-9. The following sections give more detailed accounts of each of these parameters, how they are calculated and incorporated into the hazard assessment.
