Stability of shear shallow water flows with free surface

AA Chesnokov, GA El, SL Gavrilyuk, MV Pavlov - SIAM Journal on Applied …, 2017 - SIAM
Stability of inviscid shear shallow water flows with free surface is studied in the framework of
the Benney equations. This is done by investigating the generalized hyperbolicity of the …

Hamiltonian fluid reductions of electromagnetic drift-kinetic equations for an arbitrary number of moments
