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
Features
In addition to use in the TransformationModule, rating curves can be visualized, modified , exported and imported.
An overview of features associated with rating curves is provided below.
- rating curves can be visualized in a graph in 04 Data Display and Data Editor
- rating curves can be modifed in Modifiers Display, using <ratingCurveModifiers> described in 25 ModifierTypes
rating curves can be exported with exportRatingCurveActivity described in 05 General Adapter Module
rating curves can be exported to the Open Archive using exportRatingCurves section of 22-2 Export to Deltares Open Archive
- rating curves can be imported from the Open Archive using importRatingCurves section of 22-3 Import from Deltares Open Archive
rating curves can be imported with <importTypeStandard>pi_ratingcurves</importTypeStandard> in TimeSeriesImport module
Obsolete rating curves
If a configuration still has obsolete rating curves (19 Rating curves (Obsolete since 2009) - EOL) , these rating curves can be used only in transformation module and do not support features as described above.
