  We consider the general Degasperis-Procesi model of shallow water out-flows.
This fife parametric family of conservation laws contains, in particular, KdV,
Camassa-Holm, and Degasperis-Procesi equations. The main result consists of a
criterion which guarantees the existence of a smooth soliton type solution. We
discuss also the scenario of soliton interaction for this model in the
nonintegrable case.
