Splet13. mar. 2002 · The rational method uses a constant intensity storm for its model. The SCS method uses a storm that is initially gentle but that has a period of much greater intensity at some time during the event. The second largest factor is the difference in the runoff factors. SpletA TR-55 computer program is now available, based closely on the manual calculations of TR-55. 2) TR-55 utilizes the SCS runoff equation to predict the peak rate of runoff as well …
