摘要: 构建基于元胞自动机的河道水流漫延模型,在该模型中针对河道地形特点处理边界问题,基于水力学中的曼宁公式构建模型局部转换规则,并利用元胞自动机的模拟空间复杂系统动态演变能力的特点,模拟了水流由上断面向下断面流动的动态过程,形成符合上下断面水位的水面,进而计算河道槽蓄量。实验结果表明,把元胞自动机模型引入水文领域计算河道槽蓄量的方法具有可行性。Abstract: We propose a river flow spreading model based on CA in this paper.In the model,we process the boundary based on the feature of river DEM,and define the transition rules according to Manning Equation in the field of hydrology.According to the character that CA can simulate the dynamic process of space complex system,we simulate the dynamic process of river flow from up-section to down-section,then we compute the river storage when the water levels of up-section and down-section meet the requirements.The experimental results show that the method of computing river storage based on CA is feasible.
