In watershed hydrology, the time of concentration is the time required for runoff from:
Correct answer: A. The hydraulically most distant point to reach the outlet
- A. The hydraulically most distant point to reach the outlet
- B. The outlet to reach the watershed divide
- C. The river to reach its bankfull stage
- D. A reservoir to fill to its normal level
Explanation
The time of concentration is the travel time from the hydraulically most distant point in a catchment to its outlet. After this time, runoff from the whole catchment can contribute to the outlet flow.

About Hydraulics and Water Resources
Hydraulics studies fluid properties, pressure, buoyancy, continuity, Bernoulli's equation, momentum, pipe flow, open-channel flow and hydraulic machines. Water resources extends these principles to pumps, turbines, reservoirs, irrigation, floods and hydrology, while distinguishing laminar from turbulent flow and uniform from gradually varied channel flow.
