About Cubic metres per second
The cubic metre per second (m³/s) is the SI coherent unit of volumetric flow rate. It is used for large river discharges, turbine inlet flows, and major pipeline capacities. The Amazon River at its mouth averages ≈200 000 m³/s; a large hydroelectric turbine passes 400-800 m³/s; a major municipal water-main carries 5-20 m³/s. 1 m³/s = 1 000 L/s ≈ 15 850 US gal/min = 35.315 ft³/s.
About Acre-feet per second
The acre-foot per second (ac-ft/s) equals 1233.48183754752 m³/s, an enormous unit representing the flow that would fill a football-field-sized area to 1 ft depth every second. It appears in descriptions of exceptionally large dam-break flood waves and major river-system extreme events. The 1976 Teton Dam collapse peak outflow was estimated at ≈65 000 ft³/s ≈ 1.49 ac-ft/s. 1 ac-ft/s = 1 233.48 m³/s.
