Cumec (m³/s)
A cumec is one cubic metre per second, the SI unit of river, canal and flood discharge. The Ganga at Farakka carries about 10,000–60,000 cumecs in the monsoon.
Symbol: m³/s (ASCII: m3/s)
Quantity: volumetric discharge of rivers, canals and water supply
SI relation: m³/s is the coherent SI unit of water discharge.
Derivation: 1 cumec = 1 m³/s.
Exact: yes, by definition
Typical uses
- River and flood discharge
- Canal and spillway design
- Hydrographs and flood routing
