P-ROUTE, a screening-level Pollutant Routing model is a simple routing model that estimates aqueous point and non-point source pollutant concentrations on a reach by reach flow basis, using 7Q10 or mean flow.

  It is a Windows-based interface which can estimate surface water concentrations, based on point and non-point source inputs.

P-ROUTE is similar to the Routing and Graphical Display System (RGDS) model; however it utilizes an improved method of estimating average reach concentration of a pollutant.
  1. Downstream modeling of point and non-point source pollutants,
  2. Identification of discharge facilities by reach of all modeled reaches,
  3. Identification of points for water sampling or withdrawal and the calculation of the final concentration for each of these points,
  4. Identification of a non-point load for each modeled reach, and
  5. The system supports transport and decay for two flow regimes: 7Q10 low flow and mean flow.
