Abstract
We prove existence of Steiner symmetric maximizers for a constrained variational problem in ℝ2. Solutions represent steady geophysical flows over a surface of variable height. The kinetic energy is maximized with respect to the set formed by intersecting a set of rearrangements of a given function with an affine subspace of codimension one.
