Abstract

This paper mainly focuses on the construction of the collaborative virtual geographic environment (CVGE) system, which supports the cooperative risk assessment and impact analysis of dam-break in Barrier Lake. The risk assessment flowchart of dam-break in Barrier Lake was firstly designed. Then the CVGE system framework was proposed. Meantime some key technologies including the distributed scene modeling, the collaborative workflow and the dynamic group control mechanism were also discussed in detail. Finally, a prototype system was implemented to support collaborative risk assessment of dam-break in Xiaojiaqiao Barrier Lake in Anxian county, Sichuan province. The results prove that the scheme addressed in the paper can improve the efficiency of the forecasting analysis and the emergency response of dam-break risk in Barrier Lake.
