The problem on the behavior of a solitary wave passing 
over different types of underwater barriers is considered. The problem 
has been solved numerically using the method of the correction of 
flows. The parameters of the method of solution have been selected. 
The results are compared with the Korteweg-de Vries theory. The 
interaction of two solitary waves is simulated and it is shown that 
they possess the properties of solitons. After the interaction, their 
shape and velocity remain constant; it is only the phase that undergoes 
a change. The case of disintegration of the initial perturbation in 
a cylindrically symmetric problem is considered.
