Cited topics are (i) theory for nonlinear longwaves on a coastal density current and the propagation of a density front along a coast, (ii) instabilities contained in one-layer frontal models, and (iii) nonlinear stability theory of two-layer boundary currents. Although much of these works were carried out by using frontal models, results obtained under the quasi-geostrophic approximation are also reviewed.
