About US barrels per second
The US barrel per second (bbl/s) equals 0.158987294928 m³/s, an extremely large flow rate used only for catastrophic spill-rate estimates and very large pipeline surge calculations. The 2010 Deepwater Horizon spill peaked at ≈60 000 bbl/d ≈ 0.000694 bbl/s; major subsea pipeline ruptures may briefly exceed 1 bbl/s during decompression. 1 US bbl/s = 0.158987 m³/s ≈ 158.987 L/s.
About Cubic kilometres per year
The cubic kilometre per year (km³/yr) equals 10⁹/(365.25×86400) ≈ 31.688 m³/s, the unit used in global hydrology, glaciology, and climate science for river basin runoff, ice-sheet mass balance, and groundwater storage change. Total global freshwater river runoff is ≈37 000 km³/yr; the Amazon alone contributes ≈6 600 km³/yr; the Greenland ice sheet loses ≈280 km³/yr to melt and calving. 1 km³/yr ≈ 31.69 m³/s.
