About influence of boundary on the chaotic advection in barotropic quasi-geostrophic models

Barotropic inviscid model of chaotic advection in unidirectional pulsating background flow over a seamount of $\delta$ form located near to rectilinear Boundary is considered. Estimation of breadth of a boundary layer between an exterior flowing current and rotational area, in which there is an interchanging of passive impurity particles, between indicated areas are obtained. It is shown, that influences of boundary leads to breadth of that layer is increased in case of a determination of a hyperbolic point on to boundary.
