THE CHAOTIC ATTRACTOR OF THE SEDIMENT MOVEMENT

We consider the chaotic behavior of the sediment movement with the obs erved data of the Yangtze River in China and the method of the reconst ructed phase space and we find that in the sediment movement there is an attractor. As far as the real example mentioned in this paper is co ncerned, the correlation dimension and the largest Lyapunov exponent a re around 6.6 and 0.013 respectively. These results are crucially refe rential for estimating the mode of the sediment movement, designing th e scheme of the sediment observation, and studying the predictability problem of the sediment.
