Webb22 aug. 2011 · Can any more experienced hydrologists comment on if there is there a reason why I wouldn't want to use the SCS TR-55 time of concentration method with the rational method? Does the fact that TR-55 uses a 2yr-24hr event in its TOC calc make it incompatible with the Rational Method? Thanks for your comments.
