You are designing a drainage system for a residential site in Atlanta using a 10-year return period. The site has an area of 1 ha, a flow length of 100 m, an average slop of 1%, a Manning's number of 0.25 and Type B soil. Drainage regulations require that the kinematic wave equation be used to calculate the time of concentration. You are allowed to use either the rational method or TR-55 to calculate the peak runoff rate. It is suggested you used a runoff coefficient of 0.4, which is typical for residential sites. What curve number would be required for both the rational method and the TR-55 method to provide the same peak runoff rate?
