Basin Storage Volume from Excess Inflow

Easycontinuitystorage
Inflow to a basin exceeds outflow by a constant 1 m3/s for 30 minutes. What additional storage volume is required?
  1. A30 m³
  2. B300 m³
  3. C1,800 m³
  4. D3,600 m³
Show solution

Answer: C. 1,800 m³

Storage increase = net inflow × time. Convert 30 min to 1,800 s: ΔS = (1 m³/s)(1,800 s) = 1,800 m³.
