Water
The depth of flow when the Froude number equals one. The depth of flow at which the discharge is maximum for a given specific energy, or the depth at which a given discharge occurs with minimum specific energy.
The depth of water flowing in an open channel or conduit, partially filled, corresponding to one of the recognized critical velocities.
