The unit hydrograph of a catchment represents the direct runoff hydrograph resulting from:
Correct answer: A. One unit of effective rainfall over a specified duration
- A. One unit of effective rainfall over a specified duration
- B. One unit of total rainfall over an entire year
- C. Constant rainfall of any intensity for one day
- D. Groundwater flow from one observation well
Explanation
A unit hydrograph is the direct runoff response to one unit depth of effective rainfall distributed uniformly over the catchment during a specified duration. Effective rainfall excludes losses such as infiltration and evaporation.

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.
