Rating Curves Module Configuration
The ratings curve rating curves module is a standard file (i.e. it has a fixed name) which contains all the rating curves used in your system. It A rating curve is referenced by the location id. I.e. each location has a specific rating curve for that point in the river. Furthermore a rating curve can have one or more periods for which it is valid. For each location there can be different rating curves that are valid for different times.
When a transformation needs to use a rating curve for a given location at a given time, then it will search all rating curves for the given location id. From all rating curves with the given location id, it will use the rating curve that is valid for the given time. For each location and each point in time there can be only one rating curve that is valid for that location and that time.
The ratings are either "qhrelationtable" or "simpleratingcurve" refer to by the hydroMeteoFunction in the transformation module. An example of the reference from the transformation module is shown below:
...
location for which the rating is valid should be the same as in the locations.xml
ratingCurveType you can choose from either LevelToFlow or FlowToLevel
reversible if this option is set to "true" then both level to flow and flow to level calculations with be allowed
ValidPeriod allows you to enter a start and end date for which the rating is valid (i.e. a summer and winter rating)
