Abstract :
This paper introduces the application of web 3D GIS (Geographic information system) for dam-break flood modeling, including dynamic 3D visualization and spatio-temporal analysis. Distributed virtual scene modeling method was firstly introduced. Then the system framework was proposed. Meantime some key technologies including the collaborative workflow, mobile agent computing service and simulation analysis of dam-break flood modeling were also discussed in detail. Finally, authors present a 3D web-based GIS application for simulation analysis of dam-break flood modeling with a case study on Xiaojiaqiao Barrier Lake in Anxian county, Sichuan province, China. Experimental results prove that the scheme addressed in the paper is effective and feasible.
