Splet11. okt. 2006 · The original TR-55 software also had a lower limit on the time-of-concentration, which precluded it's use on very small sites. But the current NRCS Unit Hydrograph procedure (as used in TR-20, Win-TR-55, and others) can be used with very small Tc values, so this method is commonly used for small sites as well. Spletc used in TR-55 is 0.1 hour. • A culvert or bridge can act as a reservoir outlet if there is significant storage behind it.
