WebBy standard methods, conditions 1 and 2 can be shown to be satisfied by a stream function of the form \begin{equation} \label{psi} \psi(x,z) = B_0 z + \sum_{j=1}^N B_j\ \frac{\sinh(jkz)}{\cosh(jk)}\ \cos(jkx) \end{equation} where $k$ is the (as yet … WebJan 1, 1979 · A disadvantage of this method is that the wave height cannot be specified as an independent parameter. In formulating tables for the stream-function wave theory, Dean (1974) obtained the desired wave heights by computing iteratively complete solutions for different values of the total head. This is a time-consuming and costly process.
