摘要
基于小波变换研究了甘河加格达奇站年最大洪峰流量周期变化和长期预报。研究表明,加格达奇站年最大洪峰流量存在多时间尺度特征,其主要周期有4a、6a、27a;提出了基于小波变换的谐波预报方法。
Law of the flow change and long-range prediction of annual top flood peak on Jiagedaqi Station of Ganhe River is discussed in this paper, Based on wavelet transforms. It indicates that law of the flow change of annual top flood peak on Jiagedaqi Station has a characteristic with multi-time scale, and its main periods are 4 a, 6 a and 27 a. Harmonic wave prediction method is provided based on wavelet transforms.
