| Equation variables from the currently selected arc are displayed in the variables window of the ''Time Computation Attributes'' dialog. Variables such as length and slope will generally have defaulted values, however other variables such as Manning’s roughness coefficient will need to be entered before a travel time for the arc can be computed. Variables are edited by selecting the variable you want to modify from the text window and then setting the value in the adjacent edit field. The Instructions/Results window will let you know when variables have not been defined and the travel time for the arc once all variables have reasonable values.
