Through the research of integrated technology of information model for waterway regulation engineering,we carry out the secondary development of 3D GIS software CityMaker and Surfer,Autodesk Civil 3D,Mike21,and achieve that GIS data,BIM model data,data of river bed erosion and deposition,hydrodynamic simulation data,the management data of the participants in different stages of the project can be integrated efficiently and managed conveniently into GIS platform.The engineering practice shows that this technology is practicable,and can be provided reference to the application of BIM technology in waterway regulation projects.
