Progressive surface waves in elliptical channels are studied. For the special case of a circular channel, both, analytical and numerical solutions of the frequencies of longitudinal modes of progressive surface waves are considered first. The numerical solutions of the frequencies for various modes of waves propagated along the longitudinal axis of elliptical channels with various depths are solved. The frequencies obtained for elliptical channels are compared with those for rectangular channels and triangular channels for various depths. Also surface wave patterns and the free surface displacement are given for the first four longitudinal modes of progressive surface waves.
