Synchronous-asynchronous Encounter Probability of Rich-poor Precipitation between Water Source Areas and Water Receiving Areas of the Water Transfer Projects in Guizhou
The rich-poor encounter between water resources area and water receiving areas have an important effect on the formulation of scheduling scheme in Guizhou's water diversion projects .The method of Copula is used to construct the joint distribution of the water sources area and the water receiving area of annual rainfall of adjustable Central Guizhou ,and the model is used to study the rich-poor encounter rainfall between the water sources area and the water receiving areas and in different water receiving areas .The results show that ,by using the method of Copula and compared with the traditional statistics ,the combination of water runoff was greater than 75% ,but the statistical method of calculating the precision associated with sample sequence length ,and the Copula method of Copula makes up for this deficiency and in the calculation of the continuous probability of more advantages ,the results prove that using the method of Copula to describe the different hydrological regions in water transfer project in Guizhou runoff en‐countering problem is feasible .
