✦ Synopsis

The mild-slope equation, well-known in wave refraction theory, is used to calculate the natural frequencies of oscillation of fluid in a basin. The method may be applied to canals of variable cross-section and to axisymmetric basins provided that every point in the fluid lies directly beneath the free surface. Comparison is made with previously known solutions and some new results are presented for axisymmetric geometries.
