摘要: To achieve fast flood modelling for large-scale problems, a two-dimensional cellular automata based model was developed. This employs simple transition rules and weight-based system rather than complex Shallow Water Equations. The simplified feature of allows the to be implemented in parallel environments, resulting significantly improved efficiency. has been tested using an analytical solution four case studies outputs were compared those from widely-used commercial physically-based hydraulic model. Results show that is capable simulating water-depth velocity variables with reasonably good agreement benchmark model, only fraction computational time memory. In real world example, proposed run times are up 8 faster. rapid accurate attributes have demonstrated its applicability quick analysis large systems. A new (CA) technique developed.The uses minimise use equations.The implementation runs on multi-core CPUs graphics card GPUs.The can faster less memory
