dam-break floods plays a key role in emergency management and
disaster information dissemination. However, existing methods and systems for
the simulation and visualization of floods have some
deficiencies. First, the input data parameters are complex. Second, the simulation process is cumbersome and time
consuming and lacks a complete workflow. 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. Finally, two typical
dam-break flood cases are selected for experimental analysis. The experimental results show that this system can support
the rapid 3D reproduction of dam-break floods constrained by
post-disaster information. Compared with other simulation systems, the
reproduction time is reduced to hours and supports rapid reproduction at different times and positions.
