upstream rapidly

downstream rapidly

In the direction of the unbalanced force at a velocity dictated by the relative magnitude of the unbalanced force

Rapidly up and down as an oscillating jump

A balance of the specific forces

An unbalance of the specific forces acting upstream to hold the jump in position

An unbalance of the specific forces acting downstream to cause the energy loss at the jump

A balance of the specific energy
