Nov 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 ...
