RWQM The Hydrodynamic Sub Model
Hydrodynamics refers to the motion of a water body through its geo-morphological environment, taking into account the effects of gravity and friction at the water/bed interface. A hydrodynamic model simulates these effects, giving the water surface elevation and velocity in response to tidal influence and flows from upstream river tributaries. The results from the hydrodynamic model is of fundamental importance to the transport and eutrophication models, since it describes the way in which the constituents are advected throughout the model domain.
A two-dimensional (2D), vertically averaged hydrodynamic model (RMA-2) defining the distribution of velocities in Moreton Bay was developed, calibrated, and verified in 1998. This model was used to provide the necessary hydrodynamic input for the transport and eutrophication models during this study.
