The TR-55 equations for travel time are one set of commonly used equations to compute time of concentration. Others, including those used by the Federal Highways Administration, are variations of the same type of equations. These sets of equations form a library of predefined equations in WMS. However, you can also enter your own equation or modify one of the existing equations.
Equations consist of a type and sub-type (user-defined equations do not require a sub-type). Both are specified using the drop-down combo boxes in the attribute dialog.
