This is the first book on explosion-generated water waves. It presents the theoretical foundations and experimental results of the generation and propagation of impulsively generated waves resulting from underwater explosions. Many of the theories and concepts presented herein are applicable to other types of water waves, in particular, tsunamis and waves generated by the fall of a meteorite. Linear and nonlinear theories, as well as experimental calibrations, are presented for cases of deep and shallow water explosions. Propagation of transient waves on dissipative, nonuniform bathymetries together with laboratory simulations are analyzed and discussed.
Excerpt from Water Waves Produced by Explosions In our analysis we assume that the surface elevation n and the accompanying water motion, are symmetric about an axis through the center of the disturbance. If r denotes distance from this axis and t denotes time then we may write n We also assume that the water is of finite uniform depth, which we denote by h and that the linear theory of surface waves is applicable. Both of these assumptions will be analysed in a later report. In the next two sections we present and discuss the results of our analyses for the cases of initial impulse and initial displacement respectively. Typical graphs of the wave height as a function of r and of t are included. Then in section IV these resulte are applied to the problem of wave production by explosions. The mathematical analysis is contained in an appendix. A list of references to previous work on this subject is appended. Of the previous work the earliest, that of Poisson is the most relevant. However he considers water of infinite depth. Furthermore he obtains detailed results only for paraboloidal and ellipsoidal depressions. Burnside [h] also considers infinite depth, but only twodimensional motion. He obtains a series for the wave motion produced by an initial elevation of very spe01al shape.

The objective of this report is to combine all theoretical efforts to date and new theoretical developments under this contract into an effective method for predicting the surface water wave spectrum generated by surface or underwater explosions. Particular importance has been stressed on the data presentation in order to facilitate the use of this prediction method by those unfamiliar with the complicated analysis of the phenomena involved. The data is presented, in large, by graphical means and the user may obtain all pertinent information about the initial wave envelope by merely reading a series of graphs and performing some elementary multiplications. More detailed information about the actual waves present in the envelope may be obtained by some table searching and a minimal number of elementary multiplications. (Author).
The problem of external forces and problems involving the action of an explosion on a structure are investigated. These problems are of interest to engineers, designers, and scientific workers. The following 4 studies were made: 1. General Laws Governing the Propagation of Shock Waves, 2. Explosion in an Unbounded Medium, 3. Simplest Boundary Problems of Explosion Theory, and 4. Principal Aspects of the Problem of External Forces in the Case of Aerial and Underwater Explosions. (Author).
