Abstract: In this paper it is shown that a harmonic Riemannian foliation of a Riemannian manifold can be characterized as being a critical point of the energy of the foliation under certain variations of the manifold's Riemannian metric. These variations are those induced by the flows of vector fields on the manifold.
