Abstract : The purpose of this report is to develop a model of the physical processes which occur in the upper critical depth problem. The model is solved numerically and predicts the impulse applied to the water as a function of time. This physical model focuses upon the importance of the impulse applied to the water, as suggested by Sakurai. Further observations were taken from full numerical calculations made by Bjork and Gittings. These ideas were then synthesized with further calculations to develop a model which approximates the intricate two dimensional flow of the explosive products by a one dimensional flow pattern.
