A theorem showing the way to obtain exact particular solutions of a system of two first-order quasilinear equations is proved. The use of this theorem is demonstrated on the shallow-water equations.
In all described cases, use of the theorem leads to exact particular solutions in parametric form, obtained by solving simpler systems which are reduced to ordinary differential equations through separation of variables.
