Which mechanism impacts hydraulic jump behaviour at varying Froude numbers?

A)Increased hydrostatic pressure above critical depth
B)Dominant viscous forces stabilize flow
C)Kinetic diffusion reverses momentum transfer
D)Suppressed gravity waves facilitate calm transition

💡 Explanation

A hydraulic jump's behaviour is affected by the balance of inertia and gravity described by the Froude number; above critical values, increased hydrostatic pressure dominates, therefore momentum dissipates into a turbulent transition, rather than allowing for the formation of standing waves because gravitational forces are overcome.
