This paper describes the numerical simulation of flow hydrodynamics within a wetland. Using data collected from a field-based investigation of wetland hydrodynamics in the Monash University Research Wetland, a two-dimensional model was developed and calibrated. MIKE 21, a two-dimensional depth averaged model developed by the Danish Hydraulic Institute was used to undertake the simulations. Field observation found that hydraulic roughness, as reflected in the different zones of vegetation, and the relationship between water depth and vegetation, were the factors that controlled flow within the wetland. However, calibration of the model found eddy viscosity was the key calibration parameter due to the flow within the wetland being dominated by inertia rather than friction.
