Overview
RatingCurves.xml is a standard file (i.e. it has a fixed name) which contains all the rating curves used in your system. The rating curves can be used in transformation module to convert a stage to a discharge and vice versa.
A rating curve is referenced by the location id, i.e. each location has a specific rating curve for that point in the river.
A rating curve has a valid period specified with a start date and optionally with an end date.
It is possible to have different rating curves with the same location id and different valid periods . The valid periods can overlap. A rating curve is valid until the next rating curve with the next start date becomes valid.
When the transformation module needs to use a rating curve for a given location at a given system time, it will use the rating curve that has the system time in its valid period.
Configuration
Rating curve configuration details and examples can be found in the paragraph 25 PI-rating curve
