In this Thesis, the influence of one-dimensional nonlinear effects at tsunami modeling is discussed and compared with its linearization. Beside that, the numerical simulation of two-dimensional nonlinear effects at tsunami modeling is conducted by flat topography. The linearization solution of one-dimensional model at tsunami can be found by linear hyperbolic system while the solution approach nonlinear effects at tsunami modeling of one-dimensional and twodimensional can be figured out by Lax-Wendroff method. Numerical simulation is given to ilustrate the results.
