The Rational Method is one of the simplest and best known methods routinely applied in urban hydrology. Peak flows are computed from the simple
equation:
Q = kCiA
where:
Q - Peak flow
k - conversion factor
C - Runoff coefficient
i - Rainfall intensity
A - Catchment area
With WMS' capability to create TINs from feature arc data, roads, railroads, canals, and other urban features which control runoff are easily
incorporated into the model so that an urban catchment area can be delineated so that the variable A can be automatically computed.
