Anchor: #i1107984 Section 11: Time of Concentration Time of concentration (t c) is the time required for an entire watershed to contribute to runoff at the point of interest for hydraulic design; this time is calculated as the time for runoff to flow from the most hydraulically remote point of the drainage area to the point under investigation

Time of concentration and design return period are used to determine the rainfall intensity for the design storm, to be used in the Rational Method calculation of peak runoff rate, which is used for design of stormwater management structures, such as storm sewers, stormwater inlets, and stormwater detention structur The duration of the design storm must be equal to the time of concentration .
