subcritical

8.1
A flow slower than surface waves so waves can move upstream
  • adjective
  • /sʌbˈkrɪtɪkəl/
  • Specialized
translation icon : subcrítico
  • The subcritical flow allowed the waves to travel upstream.

Examples

  • In subcritical flow, disturbances can move both upstream and downstream in the channel.

  • The design of the dam must account for subcritical conditions to ensure safety during floods.

  • Engineers measured the river and confirmed it was in a subcritical state after the rainfall.

  • In this experiment, the conditions are subcritical.

Morphology

subcritical = critical (semi-transparent) = sub + critical

Segmentation is clear (sub- + critical), but the hydrodynamic meaning of 'critical' (related to wave speed/flow regimes) is technical and not necessarily inferable by general learners.

Etymology

Subcritical is formed from sub- 'below' and critical 'an important limit', and in water flow this means the speed is 'below' the speed of surface waves. So subcritical flow lets waves and disturbances move upstream as well as downstream.
