Abstract
The reductions of the Benney moment equations to systems
of finitely many partial
differential equations are discussed. These satisfy a compatibility
condition, and
the reduced equations are diagonalisable and semi-Hamiltonian.
By imposing a further
constraint, of scaling and Galilean invariance, the compatibility
condition is reduced
to a system of algebraic equations, whose solutions are described.
