Studies on the scalability of the nonlinear phenomena strength of the three-dimensional shallow water wave equation
Hosoyamada Tokuzou
In the present, the simulation numbers of flood, river flow, tsunamis, etc. have been calculated using methods as the Lattice Boltzmann method, NS Equation direct calculation method, the Shallow water equation, and others. The Shallow water equation is consider the classical method, and is widely use in the civil engineering field. This method is develop in 1D, 2D and 3 Dimensions; in 1D and 2D calculations, the method is very effective when the vertical scale is very small compared with the horizontal scale. This is the reason why this method is use in many calculations. However, when the method is use in 3D calculations there is a problem to the attachment of certain restrictions.
In the present, there are some researches to ascertain the possibility of extending the calculations that were eliminated due to the restrictions. If this is possible, then we can assign the grid to the water surface and also to the inner ground, so we can consider also the permeability and the ground deformations. This thesis presents the approaches utilized with Fortran to verify the possibility about using the Shallow water equation methods in 3 Dimensions calulations.
In this study, the investigation and analysis is to examine the dam break phenomenon when there is a water column in the center.
