Use the Velocity Boundary to specify a supercritical flow boundary.

Parameters are:

•Start Time

•Head (Flow Depth)

•Velocity in the X-direction at the corresponding start time

•Velocity in the Y-direction at the corresponding start time

•Valid Time Intervals

The Froude Number, a non-editable parameter, is also displayed.

A Froude Number of more than one is required for a valid Supercritical Boundary

The Supercritical Boundary is only applied:

•If no Valid Time Intervals are defined; or the

•Model time corresponds to a Valid Time Interval; and the

•Froude Number exceeds one.
