Frequently Asked Questions (FAQ)

For the new Tc calculation (using a spread sheet), can the results be directly used in Mora?

The time of concentration (TC) calculated using the spread sheet can be used as an input data for the MORA. The numbers (TC's) have to be typed in subarea by subarea into the MORA input file in order to run the MORA program. The time of concentration is one of the parameters that is needed to run the MORA program. The other parameters are - percent impervious value, soil number, rainfall mass curve number, subarea area, conveyance type, conveyance length, conveyance slope, etc.
