Forecast the suspended load baron chay river by chaos theory
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2014, Vol 4, Issue 7
Abstract
Estimation of rivers suspended load is one of the major issues of topics related to river engineering, reservoirs management, schemes and hydrologic projects. The chaotic behavior of monthly precipitation time series is investigated using the phase-space reconstruction technique and the principal component analysis method. To reconstruct phase space, the time delay and embedding dimension are needed and for this purpose, average mutual information and algorithm of false nearest neighbors are used. Correlation dimension method is applied for investigating chaotic behavior of the daily suspended sediment statistics, which is the resultant of correlation dimensions, expresses chaotic behavior in the time series to illustrate efficiency of chaos theory for predicting suspended sediment, daily suspended sediment statistics of Maku Baron Chay River investigated for 5years. The delay time and optimum embedding dimension were obtained 8 and 5 respectively. The low amount of correlation dimension (d = 3) represents the chaotic behavior of sediment time series.
