The 1D water quality add-on for Flood Modeller Pro is a fully featured water quality simulator for advection/diffusion of conservative and decaying pollutants, water temperature, cohesive sediment transport, interaction of quality determinands with sediments, phytoplankton and pH.

The 1D water quality add-on can be used in conjunction with a full hydrodynamic simulation to simulate water quality processes in detail, or can be driven by Flood Modeller hydrological routing results for less detailed applications.

The user is able to specify the processes included in the simulation, providing focus on the specific needs of the particular study and improved productivity. The add-on provides water quality simulation suitable for use in many types of studies, including Water Framework Directive and Urban Pollution Management studies.

The water quality add-on is run as a post process to a 1D hydraulic simulation. The velocities and flow areas are calculated by the hydraulics and are then saved and can be used to run one or more water quality scenarios.

The add-on solves the one-dimensional advection-diffusion equation and any biochemical equations required.  Model boundaries are represented by concentration-time or concentration-flow relationships.  Pollutants can also be introduced at or removed from any point in the model.

  • Available at no cost as part of the free version of Flood Modeller Pro

  • Utilised in open channel systems, including rivers, estuaries and canals

  • Includes three different algorithms allowing the user to choose the most appropriate for their application

  • Capable of modelling a range of water quality variables and processes simultaneously

  • Used in conjunction with a full Flood Modeller hydrodynamic simulation

  • Can be driven by Flood Modeller hydrological routing results for less detailed applications

  • Pollutants can also be introduced at or removed from any point in a model
