Abstract
We consider a system of coupled partial differential equations describing pollutant transport in a river system. Symmetry analysis of this system resulted in admitted large Lie algebras for a some special cases of the arbitrary constants and the source term. Furthermore, we construct the one-dimensional optimal systems of the admitted symmetries. However, similarity (invariant) solutions for the system are constructed for some more realistic source term.
