In the Rational Method, the estimated peak runoff discharge from a small catchment is proportional to the:
Correct answer: A. Rainfall intensity
- A. Rainfall intensity
- B. Reservoir capacity
- C. Channel roughness only
- D. Groundwater table depth
Explanation
The Rational Method uses Q = CIA, so peak discharge is proportional to rainfall intensity, runoff coefficient, and drainage area. Reservoir capacity and groundwater depth are not direct terms in this formula.

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.
