These concluding remarks draw together some of the key points made in earlier chapters and highlight the more important issues involved in modelling flows in rivers. Suggestions are made about future work that is required in the area of modelling as well as possible developments in the CES-AES software. The need for accurate measurements of certain hydraulic and turbulence parameters at full scale is especially highlighted. These should be carried out in conjunction with the development and rigorous testing of improved computer-based modelling tools, tested on a selected number of rivers and against benchmark laboratory data.
