Spatial linear stability analysis of shallow mixing layers is performed in the present paper for the case where friction force varies considerably in the transverse direction. Floodplains with vegetation give practical examples of such a situation. Linear stability problem is formulated for the case where friction coefficient is a function of the transverse coordinate. Numerical results show that growth rates for the case of variable friction are larger than for the case of constant friction.
