We present a review of river models. The prediction of the transport and fate of nuclides in rivers is highly complex, because it involves consideration of transport mechanisms, river geometry, flow and hydraulic properties. A brief discussion on the transport and behavior of particle-reactive nuclides is presented using phosphorus, a reactive nuclide which has been intensely studied in river systems, as an example. A description of a conceptual river transport model is also presented. In the report, river transport models are grouped into the following categories: empirical modes, nutrient spiraling models, numerical models, and random walk models. The application of these models to nuclear fuel waste management is discussed.
