Time Series Analysis of Flow and Sediment Discharge in Yellow River Estuary

摘要

The runoff and sediment in the Yellow River Delta is significant to therncontinuous economic development and ecological environmentrnevolution. The analysis of the flow and sediment can provide anrnimportant basis for the future control of the River Delta. According tornthe survey data from 1950~2007 of Linjin hydrologic station,rnprobability statistics and time series method such as Kendall method,rnorder clustering method are applied to analyze the runoff and sedimentrndischarge. The results show that the flow and sediment have beenrndeclining obviously over the past 60 years, and the change decreasesrnmainly in the form of jumping. The reasons of the variations of flowrnand sediment are also discussed in this paper.
