Study on flood spreading model of Hongze Lake based on cellular automata
基于元胞自动机的洪泽湖洪水蔓延模型研究

Basic principle and structure of Cellular Automata (CA) was analyzed, and flood spreading model of Hongze Lake was established by making use of CA rule. Based on grid spatial data structure, adopting the two-dimensional CA model, the cellular space and cellular states were established, and the rule for flood spreading modeling was made. The update of the cellular sate acted according to the rule of 9 neighbors. The computed data by choosing typical index was tested. The results show that two-dimensional CA model can model the flood spreading process more simply and faster.
