A new method has been described for the analysis of transient phenomena of a hydrodynamic system having a free surface, taking the case of the Bay of Nagasaki as an example. The main operation of the analysis was carried out by an electric network being analogous to the hydrodynamic system and by an electric analogue computer designed for this purpose. In this method, some newly designed techniques for the hydraulic experi-ments have been used to determined the constants of the above network, and these techni-ques themselves may be applied independently to the general hydraulic experiments.
