= Kelvin-wave channel invariant
{c}

Exponentially weighted cross-channel integrals of <velocity> and <pressure> isolate the two oppositely propagating boundary <Kelvin waves>. Their conserved characteristic amplitudes supply the two integral constraints missing from a channel geostrophic-adjustment problem.
