In hydrology, the part of precipitation that reaches a stream channel relatively soon after a storm is called:
Correct answer: B. Direct runoff
- A. Base flow
- B. Direct runoff
- C. Interception loss
- D. Groundwater recharge
Explanation
Direct runoff is the rainfall excess that reaches a stream soon after precipitation, producing the rapid rise of a flood hydrograph. Base flow is the slower contribution mainly supplied by groundwater.

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.
