About Cubic yards per minute
The cubic yard per minute (yd³/min) equals 0.764554857984/60 ≈ 0.012743 m³/s, used in ready-mix concrete delivery rates (a concrete truck discharges 8-10 yd³ in about 10 min = 0.8-1 yd³/min) and dredge pump throughput in US harbour projects. 1 yd³/min ≈ 0.012743 m³/s = 12.74 L/s ≈ 200.0 US gal/min.
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.
