WMS:Quick Tour - Travel Time Computations
From XMS Wiki
Jump to navigationJump to search
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.
