WMS includes two different methods for computing travel times such as lag time and time of concentration.
With the first method, geometric parameters computed from a TIN or DEM are used in empirical equations developed for either time of concentration or lag time. Each sub-basin can use one equation. Coefficients and parameters used in the equation may be individually edited. All information used in computing the travel time may be saved in a text file or copied to the clipboard for documentation purposes.
