Calculations of eigencurves have been made for the three cases of rotating rectangular, trapezoidal, and circular segment basins, all with flat bottoms. These eigencurves yield eigenfrequencies for basins of given geometry and rotation or conversely, geometry and rotational parameters for a given frequency. Using these curves to obtain an eigenfrequency, calculations of eigenmodes were also made for selected basins representative of the three classes. The computations agree well with previously obtained results and indicate that the multimode transport approach to these problems is a viable one.
