Abstract: This paper presents numerical model results for a lab-scale model of the River Blackwater in Hampshire, England. This river is of interest due to the differential meandering between the main channel and the floodplain. The Delft3D code is used due to the range of turbulence models available for evaluation and the inclusion of both 2D and 3D formulations on the same finite difference grids. The numerical modelling investigates which turbulence model is most appropriate and whether there are any advantages to the more computationally demanding 3D model. Both qualitative and quantitative comparisons are made and discussed. Ultimately conclusions are drawn to inform future work at both laboratory and full scale.
