Welcome to the RAS Solution Forums HEC-RAS Help How do I show CN number instead of abstraction ratio in final value maps

    When I use an SCS curve number infiltration layer in a 2D model, RAS Mapper’s “Final value” maps always show the abstraction ratio, and I cannot find a way to make it show the Curve Number instead, which would be more useful.
    However, my colleague has somehow managed to create a project where the “Final value” shows Curve Number for geometries associated with one particular infiltration layer. When viewing the classification parameters for this layer, I also see that the Curve Number column is to the left of the Abstraction Ratio column, whereas usually it is to the right of it – I presume this is related, but she has no idea how this happened, and I can’t figure out how to achieve it either.
    Does anyone know how to control this?

    Thanks.

    OK, it doesn’t make any sense, but I see it depends what “additional shapefile data” is imported when creating the layer (i.e. with the “Add Field” button).
    – If I don’t add any fields, the CN numbers are mapped as “Final value”.
    – If I add a field for CN value, the CN numbers are mapped as “Final value”.
    – If I add a field for CN value and another for abstraction ratio, the abstraction ratios are mapped as “Final value”.
