TRACER modelling solute transport processes, consisting of advection, dispersion and mass reduction/generation by physical, chemical and biological mechanisms. TRACER is the transport and water quality module of the 1D free surface code MASCARET. TRACER simulates the evolution of several coupled tracers without retroaction on the flow with respect to hydraulic conditions, boundary conditions, external sources and biochemical interactions between tracers.
