Lesson 11: Rational Method Step 5: Calculating Time of ...
ewrel.fiu.eduNov 18, 2013 · Total Time of Concentration. The time of concentration along our sample hydraulic path is simply the sum of the travel times for the overland flow, shallow concentrated flow, and channel flow. T. c = L. o + L. sc + L. c. In our example, the time of concentration is calculated as follows: T. c = 31.5 + 3.57 + 0. T. c = 35.07 So, the time of ...

www.cedengineering.comJun 17, 1986 · watershed, the time of concentration is the time required for rainfall landing on the farthest point of the watershed to reach the watershed outlet. The time of concentration should be used as the duration of the design storm for calculating peak storm water runoff rate with the Rational Method equation. This is because a storm of duration less ...

Time of Concentration (T ): The T - Civil Engineering
www-ce.engr.ccny.cuny.eduTime of Concentration (T c): The Tc is most often defined as the time required for a particle of water to travel from the most hydrologically remote point in the watershed to the point of collection. Or The maximum or peak runoff rate from small areas usually results from a rain that covers the
