Webb9 juli 2010 · Storm & Sanitary Sewer Analysis Question. I've set up a model with numerous sub basins, links, junctions, etc. When I run an SCS-TR-20 analysis i get some strange results. For example, one of my sub basins is only 0.4 acres with a computed peak flow of 1.02 cfs for a 2 yr-24hr storm. The inlet it drains to also shows a 1.02 cfs peak flow. WebbA 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 … care specialty pharmacy

For example: if I a/P in Exhibit 2-II is < 0.1, use 0.1; and if I a/P is > 0.5, use 0.5. WebbTR-55 Method (NRCS Velocity Method) Tc is broken into 3-components or segments as prescribed by TR55 and is also known as the NRCS Velocity method. The final Tc is the sum total of the three components. Tc = TSheet + TShallow + TChannel Slopes are inputted in percent in Hydrology Studio, not ft/ft as in TR55. Sheet Flow Time care sphere
