Propagation of a soliton and generation of a tail by the soliton arc investigatedanalytically and numerically for Korteweg-de Vries equation with dissipationterm. The analytical solution obtained by the modified conservation laws showsthat the amplitude and velocity of a soliton change in time due to the dissipation.At the same time, a non-soliton part -a tail -appears in the solution. The structureof a tail depends on the dissipation term. Ntunerical solutions confirm qualitativelythe validity of the analytical solution. An overtaking collision of two solitonsis also examined numerically.
