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。
Based on Cellular Automaton, a model of the local water diversion was built. The model was applied to deal with the boundary problem based on the river topographic features. Based on the Manning formula in hydraulics, the local transformation rules of the model were constructed. Evolutionary characteristics of the simulation of the flow down the cross-section of the flow from the vertical section of the dynamic process to form a water level in line with the upper and lower sections of the surface, and then calculate the flume volume. The experimental results show that it is feasible to introduce Cellular Automata model into the hydrology field to calculate the channel reserve.
