Which reservoir function helps maintain water availability during periods of low river flow?
Correct answer: A. Storing excess water for later release
- A. Storing excess water for later release
- B. Increasing rainfall over the catchment
- C. Removing all sediment from the river
- D. Preventing evaporation from the water surface
Explanation
Reservoir storage balances variations between inflow and demand by retaining water during periods of high flow and releasing it during low flow. It cannot eliminate rainfall variation or completely prevent 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.
