Allows the user to change the hazard definitions used for a water surface file to any of the installed hazards, or a hazards definition file (.csv), as well as access the Flood Hazards Manager for managing and creating new hazard definitions
The user specifies the water surface file to change hazards (.wrb or.wrr) and the hazard definition file.
Generally, hazards should be recalculated across the entire time series to ensure that the true maximum hazard is determined. However, there are two options change hazards for a "peaks only" dataset:
- by calculating hazards using peak Velocity and peak Depth (not strictly correct) as these are not necessarily coincident
- by changing to the Australian Rainfall and Runoff (2016) Hazard Categories - in this case peak D, peak V and peak VxD values in the peaks will be used to, correctly, determine H1-H6 hazard categories. All result items must be present for accurate output.
