摘要：

In this work, we present a HLLC scheme modification for application to non-homogeneous shallow-water equations with pollutant transport. This new version is related to the definition of a consistent approximation of the intermediated wave speed. Numerical results are presented to illustrate the importance of such approximation to get appropriate pollutant concentration profiles.
