The analyze of the rivers and runoff evolution feature on the basis of complexity theory
This paper use approximate entropy of the complexity theory to study the runoff duration arrays evolution feature and rivers prediction problems. Through analyze the approximate entropy s relative change of the different rivers on Yellow River mainstream, revealed some dynamic feature of the river evolution .The analyze indicated that the approximate entropys unusual change feature, low/high behind the high/low, could be used as the evolution feature of the rivers change after the peak value/foot value, lead to some remarkable change law of the time and space structure evolution from some disorder /order state to order (disorder or random) state. The two unusual change characteristic and rivers evolution feature were just as lighting and thumping, provided certain basis to predicate the peak value.
