Home Forums RORB – general use Apply direct and indirect impervious fractions Reply To: Apply direct and indirect impervious fractions


Hi All,

I have received an old RORB model file (cat) which contain “Total Impervious Area” values. I want to run the existing RORB model with ARR19 rainfall data and include direct and indirect impervious fractions.

When I adjust the TIA to EIA/ICA values in the data tab, all of a sudden I receive a data error in my catg file (Data error: possibly character data where numerical value expected, or illegal number). I am a little perplexed as to why this error does not show up when running with TIA values only but spits out an error when using EIA/ICA values.

I have attached the catg file just in case.

thank you in advance.
