Abstract : Long barotropic seiches are investigated in a basin of constant depth bounded by curves of an eliptical-hyperbolic coordinate system. Both planetary and gravitational seiches are evaluated numerically by an iteration procedure. It is found that the frequencies of the gravitational seiches decrease with decreasing width of the narrow waist of the basin, in accordance with the theory of the Helmholz resonator, and the strongest currents are found in the waist of the basin. For planetary seiches, the frequencies generally increase with decreasing width of the waist, tho not dramatically, and the associated currents are weakest in the narrow waist. (Author)
