Development and applications of simulating technology for river flow and sediment in water transport engineering domain of China

The development and applications of simulating technology for river flow and sediment in water transport engineering domain of China have been summarized systematically.In this paper,the progress of calculation methods and simulation systems in recent years were analyzed,and examples of its application for 1-D,2-D and 3-D mathematical models were given.At present,1-D and 2-D mathematical models have already reached a relatively riper stages,3-D mathematical model can also solve some engineering problems.The future development of simulating technology for river flow and sediment include the following areas.The first is the innovation of theories on flow and sediment transport.The second is the improvement on observation technology and observation data systematic and opened to public.The third is the whole set of numerical simulating technologies and make the models opened to public,verified and used by public.
