Practice mode Water Management

A hydraulic jump forms downstream of the toe of a glacis to dissipate surplus energy. Which number governs the nature and strength of the jump?

Correct answer A. Froude number

Explanation

The Froude number, the ratio of inertial to gravity forces, classifies hydraulic jumps; higher incoming Froude numbers produce stronger jumps with greater energy loss.
