Abstract: The detonation of an explosive charge under water-surface causes complex sequences of physical phenomena to occur, appreciably changing in the ambient parameters after the explosion. The main purpose of this paper is the description of underwater detonation used for effects against targets on the water and under water. In the first step, the paper will shed light many concepts and equations describing the phenomena during underwater detonation such as: shock waves, the effect of the free surface of water and the gas bubble resulting from the detonation of the explosive charge. In the second stage, this work will be provided by modeling and numerical simulation, using MATLAB, to estimate the parameters of gas bubbles. The simulation results could be regarded as an important reference in the optimal design of the hydrodynamic characteristics of underwater detonation also it may provide information to look into the details of fluid (water) model appearance. Keywords: underwater explosion, shock wave, gas bubble, numerical modeling, numerical simulation.
