A rapid 3D reproduction system of dam-break floods constrained by post-disaster information

The 3D reproduction of dam-break floods plays a key role in emergency management and disaster information dissemination. However, existing systems for the simulation of floods have some deficiencies. First, the input data parameters are complex. Second, the simulation process is cumbersome and time consuming, and it lacks a complete workflow. In this paper, we develop a platform for the rapid 3D reproduction of dam-break floods. Key technologies, such as numerical models of dam-break floods based on cellular automata (CA), 3D reproduction constrained by post-disaster information, and dynamic augmented representation, are discussed in detail. Then, two typical dam-break flood cases are selected for experimental analysis. The experimental results show that the system can support the rapid 3D reproduction of dam-break floods constrained by post-disaster information. Compared with that of other simulation systems, the reproduction time is reduced to less than 1 h, and this system supports rapid reproduction at different times and positions.

Automated summary

This study developed a platform for rapid 3D reproduction of dam-break floods, utilizing key technologies such as CA-based numerical models, post-disaster information-constrained reproduction, and dynamic augmented representation. Experimental results demonstrated that the system can achieve rapid reproduction in less than 1 hour.
